TC74LCX157F/FT/FK

TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74LCX157F,TC74LCX157FT,TC74LCX157FK

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

TC74LCX157F

operation while maintaining the CMOS low power dissipation.

The device is designed for low-voltage (3.3 V) V

applications,

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.

TC74LCX157FT

All inputs are equipped with protection circuits against static

discharge.

Features

•

= 1.65 to 3.6 V

High-speed operation: t = 5.8 ns (max) (V

= 3.0 to 3.6 V)

Ouput current: |I |/I

= 24 mA (min) (V

= 3.0 V)

OH OL

Latch-up performance: ＞±500 mA
