SN74LVC125A

SCAS290Q – JANUARY 1993 – REVISED JANUARY 2015

SN74LVC125A Quadruple Bus Buffer Gate With 3-State Outputs

1 Features

3 Description

This quadruple bus buffer gate is designed for 1.65-V

1

•

3-State Outputs

•

Separate OE for all 4 buffers

The SN74LVC125A device features independent line

•

Operates From 1.65 V to 3.6 V

drivers with 3-state outputs. Each output is disabled

•

Specified From –40°C to 85°C

when the associated output-enable (OE) input is high.

and –40°C to 125°C

To ensure the high-impedance state during power up

•

Inputs Accept Voltages to 5.5 V

•

pullup resistor; the minimum value of the resistor is

determined by the current-sinking capability of the

•

driver.

•

Inputs can be driven from either 3.3-V or 5-V devices.

This feature allows the use of this device as a

translator in a mixed 3.3-V/5-V system environment.

•

Latch-Up Performance Exceeds 250 mA

Per JESD 17
