CD54HCT157 TI Quad 2-Input Multiplexer Data Sheet

Description

This PDF datasheet is for the TI CD54HCT157 Multiplexer.

Texas Instruments CD54HCT157 High Speed CMOS Logic Quad 2-Input Multiplexer

The CD54HCT157 is quad 2-input multiplexer which selects four bits of data from two sources under the control of a common Select input (S).
Moving data from two groups of registers to four common output busses is a common use of these devices. The state of the Select input determines the particular register from which the data comes. They can also be used as function generators.

Features:
– Common Select Inputs
– Separate Enable Inputs
– Buffered inputs and Outputs
– Fanout (Over Temperature Range)
– Wide Operating Temperature Range
– Balanced Propagation Delay and Transition Times
– Significant Power Reduction Compared to LSTTL Logic ICs
