74HC257; 74HCT257

Quad 2-input multiplexer; 3-state

Rev. 05 — 13 January 2010

Product data sheet

1. General description

The 74HC257; 74HCT257 are high-speed Si-gate CMOS devices and are pin compatible

with Low-power Schottky TTL (LSTTL).

The 74HC257 and 74HCT257 have four identical 2-input multiplexers with 3-state outputs,

which select 4 bits of data from two sources and are controlled by a common data select

input (S).

The data inputs from source 0 (1I0 to 4I0) are selected when input S is LOW and the data

inputs from source 1 (1I1 to 4I1) are selected when S is HIGH. Data appears at the

outputs (1Y to 4Y) in true (non-inverting) form from the selected inputs.

The 74HC257 and 74HCT257 are the logic implementation of a 4-pole, 2-position switch,

where the position of the switch is determined by the logic levels applied to S. The outputs

are forced to a high-impedance OFF-state when OE is HIGH.

The logic equations for the outputs are:

• (

1I1

•

1I0

•

)

• (

2I1

•

2I0

•

)

• (

3I1

•

3I0

•

)

• (

4I1

•

4I0

•

)

Except for their non-inverting (true) outputs the 74HC257; 74HCT257 are identical to the

74HC258.

2. Features

Non-inverting data path

3-state outputs interface directly with system bus

Complies with JEDEC standard no. 7A

ESD protection:

HBM JESD22-A114E exceeds 2 000 V

MM JESD22-A115-A exceeds 200 V

Multiple package options

Specified from

−40 °C

to +85

°C

and from

−40 °C

to +125

°C
