74AHCT541A

Octal buffer/line driver; 3-state

Rev. 7 — 17 March 2017

Product data sheet

1 General description

The 74AHCT541A is an 8-bit buffer/line driver with 3-state outputs and TTL inputs.

The device features two output enables (OE1 and OE2). A HIGH on OEn causes the

associated outputs to assume a high-impedance OFF-state.

Designed to operate over a V_CCrange from 4.5 V to 5.5 V, the inputs are TTL

compatible, which allows the device to be used to translate from 3.3 V to 5 V.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall

times.

This device is fully specified for partial Power-down applications using I_OFF. The I_OFF

circuitry disables the output, preventing the damaging backflow current through the

device when it is powered down.

2 Features and benefits
