74LVC257A

Quad 2-input multiplexer with 5 V tolerant inputs/outputs;

3-state

Rev. 7 — 26 June 2020 Product data sheet

1. General description

The 74LVC257A is a quad 2-input multiplexer with 3-state outputs, which select 4 bits of data

from two sources and are controlled by a common data select input (pin S). The data inputs from

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

(pins 1I1 to 4I1) are selected when pin S is HIGH. Data appears at the outputs (pins 1Y to 4Y)

in true (non-inverting) form from the selected inputs. The device is the logic implementation of a

4-pole, 2-position switch, where the position of the switch is determined by the logic levels applied

to pin S. The outputs are forced to a high-impedance OFF-state when pin OE is HIGH.

Inputs can be driven from either 3.3 V or 5.0 V devices. When disabled, up to 5.5 V can be applied

to the outputs. These features allow the use of these devices as translators in mixed 3.3 V and 5 V

applications.

2. Features and benefits

of an Nexperia product can reasonably be expected to result in personal

injury, death or severe property or environmental damage. Nexperia and its

Customers should provide appropriate design and operating safeguards to

minimize the risks associated with their applications and products.

Nexperia does not accept any liability related to any default, damage, costs

or problem which is based on any weakness or default in the customer’s

applications or products, or the application or use by customer’s third party

customer(s). Customer is responsible for doing all necessary testing for the

customer’s applications and products using Nexperia products in order to

avoid a default of the applications and the products or of the application or

use by customer’s third party customer(s). Nexperia does not accept any

liability in this respect.

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.
