Output

The TC74HC153A and TC74HC253A are high speed CMOS

DUAL 4-CHANNEL MULTIPLEXERs fabricated with silicon

They achieve the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

The TC74HC153A has standard outputs, while the

TC74HC253A has 3-state outputs.

Input data (1C0~1C2, 2C0~2C3) are selected by the two

address inputs, A and B.

Separate strobe inputs ( G

1 , G

2 ) are provided for each of the

two four-line sections. They can be used to inhibit the data

outputs. The output of the HC153A is set low, and the HC253A

output is set to the high impedance state, when the strobe inputs

are low.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features

• Output drive capability: 10 LSTTL loads

•

• Pin and function compatible with 74LS153, 74LS253

Pin Assignment

Note: xxxFN (JEDEC SOP) is not available in

Japan.
