Low Voltage Quad 2-Channel Multiplexer with 5 V Tolerant Inputs and Outputs

The TC74LCX157 is a high-performance CMOS multiplexer.

Designed for use in 3.3-V systems, it achieves high-speed

operation while maintaining the CMOS low power dissipation.

but it could be used to interface to 5-V supply environment for

inputs.

It consists of four 2-input digital multiplexers with common

SELECT and ST inputs. When the ST input is held “H” level,

selection of data is inhibited and all the outputs become “L” level.

The SELECT decoding determines whether the A or B inputs get

routed to their corresponding Y outputs.

All inputs are equipped with protection circuits against static

discharge.

Features

• Latch-up performance: −500 mA

• Available in JEDEC SOP, JEITA SOP, TSSOP and

VSSOP (US)

• Power-down protection provided on all inputs and outputs

• Pin and function compatible with the 74 series

(74AC/VHC/HC/F/ALS/LS etc.) 157 type
