TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74VCX257FT, TC74VCX257FK

Low Voltage Quad 2-Channel Multiplexer with 3.6 V Tolerant Inputs and Outputs

The TC74VCX257 is a high performance CMOS multiplexer

which is guaranteed to operate from 1.2-V to 3.6-V. Designed for

use in 1.5 V, 1.8 V, 2.5 V or 3.3 V systems, it achieves high speed

operation while maintaining the CMOS low power dissipation.

It is also designed with over voltage tolerant inputs and

outputs up to 3.6 V.

It consists of four 2-input digital multiplexers with common

SELECT and OUTPUTENABLE ( OE ).

If OE is set high the outputs are held in a high-impedance

state. 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

• 3.6 V tolerant inputs and outputs.

• Latch-up performance: −300 mA

• ESD performance: Machine model ≥ ±200 V

Human body model

≥ ±2000 V

• Package: TSSOP and VSSOP (US)

• Power down protection is provided on all inputs and outputs.
