Overview
74LV244AT Octal buffer/line driver; 3-state Rev.
1 — 23 November 2016 Product data sheet 1.
General description The 74LV244AT is an 8-bit buffer/line driver with 3-state outputs and TTL inputs.
The device features two output enables (1OE and 2OE).
A HIGH on nOE causes the associated outputs to assume a high-impedance OFF-state.
Designed to operate over a VCC range 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 IOFF.
The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
