The Texas Instruments CD54HCT157 is a High Speed CMOS Logic device functioning as a Quad 2-Input Multiplexer. It belongs to the HCT technology family and is configured as a 2:1 multiplexer with 4 channels. This military-rated component operates across a wide temperature range of -55°C to 125°C, making it suitable for demanding environments.
The CD54HCT157 offers direct LSTTL input logic compatibility and features buffered inputs and outputs. Standard outputs provide a fanout of 10 LSTTL loads, while bus driver outputs offer a fanout of 15 LSTTL loads. The device is packaged in a CDIP (J) format and is designed for through-hole mounting.
This multiplexer selects four bits of data from two sources under the control of a common Select input. The Enable input is active low. When the Enable input is high, all outputs are forced low, regardless of other input conditions. These devices are commonly used for moving data between registers and common output buses or as function generators.
