16 to 4 line encoder Electronics Forum (Circuits

Have a look at the 74148 - 8 to 3 priority encoder. If I remember correctly there is some way to cascade them. Alternatively, it can be done with a diode array. Tie each output low and have a diode from each input to each output line that has to be high. Mike. Edit, google priority encoders An IC 74148 is the most popularly used MSI encoder circuits for the 8 to 3 line priority encoder. The main characteristics of this encoder include cascading for priority encoding of n bits, code conversion, priority encoding of highest priority input line, decimal to BCD conversion, output enable-active low when all the inputs are high, etc. The inputs of digital circuits often use octal code. 10-LINE TO 4-LINE AND 8-LINE TO 3-LINE PRIORITY ENCODERS, 74148 datasheet, 74148 circuit, 74148 data sheet : TI, alldatasheet, datasheet, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes, triacs, and other semiconductors

It encodes Eight Data Lines to 3-Line Binary. Working Principle: It features priority decoding of the inputs to ensure that only the highest-order data line i Circuit Design of 4 to 16 Decoder Using 3 to 8 Decoder. A decoder circuit of the higher combination is obtained by adding two or more lower combinational circuits. 4 to 16 decoder circuit is obtained from two 3 to 8 decoder circuits or three 2 to 4 decoder circuits.. When two 3 to 8 Decoder circuits are combined the enable pin acts as the input for both the decoders 16-to-4-Line Encoder Fig 4.4.3 shows a simulation created in Logisim, which demonstrates how two 74HC148 ICs can be connected in cascade to make a 16-to-4-line encoder. Notice how EI is used to enable the most significant encoder, and how EO and EI in the centre of the diagram are used to cascade the ICs

Priority Encoder Types With Real Time Application

Priority encoders can be easily connected in arrays to make larger encoders, such as one 16-to-4 encoder made from six 4-to-2 priority encoders - four 4-to-2 encoders having the signal source connected to their inputs, and the two remaining encoders take the output of the first four as input. The priority encoder is an improvement on a simple encoder circuit, in terms of handling all possible. When two or more inputs are simultaneously active, the input with the highest priority is represented on the output. Input 7 has the highest priority. When all eight data inputs are high, all three outputs are high. Multiple 74148s can be cascaded by connecting EO of the high priority chip to EI of the low priority chip (see datasheet) These TTL encoders feature priority decoding of the inputs to ensure that only the highest-order data line is encoded. The '147 and 'LS147 encode nine data lines to four-line (8-4-2-1) BCD. The implied decimal zero condition requires no input condition as zero is encoded when all nine data lines are at a high logic level. The '148 and 'LS148 encode eight data lines to three-line (4-2-1) binary. Logi7400. Logisim 7400 series integrated circuits library.. Variants. There are two variants of the library with different circuit appearances available: In the classic Logi7400dip library, the circuit appearance reflects the physical pin layout of the DIP packaged chips.; The new Logi7400ic library provides a logical circuit appearance.; Goal. This library aims to be a comprehensive 7400. 10-Line-to-4-Line and 8-Line-to-3-Line Priority Encoders The SN74LS147 and the SN74LS148 are Priority Encoders. They provide priority decoding of the inputs to ensure that only the highest order data line is encoded. Both devices have data inputs and outputs which are active at the low logic level. The LS147 encodes nine data lines to four-line (8-4-2-1) BCD. The implied decimal zero condition.

  1. Note that multiplexers are different in operation to Encoders. Encoders are able to switch an n-bit input pattern to multiple output lines that represent the binary coded (BCD) output equivalent of the active input. We can build a simple 2-line to 1-line (2-to-1) multiplexer from basic logic NAND gates as shown. 2-input Multiplexer Design

This decoder can be used for decoding any 3-bit code to provide eight outputs, corresponding to eight different combinations of the input code. This is also called a 1 of 8 decoder, since only one of eight output lines is HIGH for a particular input combination. Fig (1): Logic diagram of 3 to 8 decoder. It is also called a binary-to-octal decoder, since the inputs represent 3-bit binary. The lower 16 bits of addresses are multiplexed on the data bus. In any operation where 8086 accesses memory or a port, the 8086 sends out the lower 16 bits of the address on the data bus. External latches such as the 74LS373 octal devices are used to grab this address and hold it during the rest of the operation. To strobe these latches at the.
