Product Overview: SN74HC157DTE4 by Texas Instruments
The SN74HC157DTE4 is a high-performance, quadruple 2-line to 1-line data selector/multiplexer designed by Texas Instruments. This integrated circuit is part of the 'HC' family, which indicates that it is fabricated using silicon-gate CMOS technology, offering the inherent advantages of high speed and low power consumption typically associated with CMOS devices.
This multiplexer device features four identical 2-line to 1-line selectors with common select inputs and separate enable inputs. It is capable of handling digital signals across a wide range, from two independent inputs for each section. Users can select between the two inputs based on the state of the select input, while the enable input can be used to disable the output in a high-impedance state, allowing for use in multiplexing applications and as a form of digital control.
