High Speed CMOS Logic 8-Input Multiplexer

The ’HC153 and ’HCT153 are dual 4- to 1-line selector/multiplexers that select one of four sources for each section by the common select inputs, S0 and S1. When the enable inputs (1E\, 2E\) are HIGH, the outputs are in the LOW state. The ’HC153 and ’HCT153 are dual 4- to... Read More

The ’HC154 and ’HCT154 are 4-to-16 line decoders/demultiplexers with two enable inputs, E1 and E2. A High on either enable input forces the output into the High state. The demultiplexing function is performed by using the four input lines, A0 to A3, to select the output lines Y0\ to Y15\,... Read More

The ’HC157, ’HCT157, ’HC158, and ’HCT158 are quad 2-input multiplexers which select four bits of data from two sources under the control of a common Select input (S). The Enable input (E\) is active Low. When (E\) is High, all of the outputs in the 158, the inverting type, (1Y\-4Y\)... Read More

The ’HC164 and ’HCT164 are 8-bit, serial-in, parallel-out, shift registers with asynchronous reset. Data is shifted on the positive edge of Clock (CLK). A LOW on the RESET (CLR) pin resets the shift register and all outputs go to the LOW state regardless of the input conditions. Two Serial Data... Read More
