SN74HCT157N Description

Short technical summary and product information.

The Texas Instruments SN74HCT157N is a high-speed CMOS TTL-compatible data selector/multiplexer. It features four independent 2-input multiplexers, each with a separate strobe input. This device is designed to select a 4-bit word from one of two sources and route it to four outputs.

 

Key electrical characteristics include an operating voltage range of 4.5V to 5.5V, with high-current outputs capable of driving up to 15 LSTTL loads. The typical propagation delay is 15 ns, and it consumes a low power of 80-µA maximum ICC. The output drive is ±6mA at 5V, and it features low input current of 1 µA maximum.

 

Packaged in a 16-PDIP through-hole configuration, the SN74HCT157N is suitable for breadboarding and through-hole PCB designs. Its operating temperature range is -40°C to 85°C, making it versatile for various environmental conditions. The device offers buffered inputs and outputs for signal integrity.

 

This multiplexer is ideal for applications requiring data selection, routing, or logic function implementation within digital systems. Its TTL-compatible inputs ensure easy integration with other logic families.
