Overview
74LVC244A; 74LVCH244A Octal buffer/line driver; 3-state Rev.
11 — 29 April 2021 Product data sheet 1.
General description The 74LVC244A; 74LVCH244A is an octal non-inverting buffer/line driver with 3-state outputs.
The 3-state outputs are controlled by the output enable inputs 1OE and 2OE.
A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.
Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise and fall times.
Inputs can be driven from either 3.
3 V or 5.
0 V devices.
In 3-state operation, outputs can handle 5 V.
These features allow the use of these devices as translators in a mixed 3.
3 V and 5 V environment.
The 74LVCH244A bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs.

Features and benefits • 5 V tolerant inputs/outputs for interfacing with 5 V logic • Wide supply voltage range from 1.
2 V to 3.
6 V • CMOS low-power consumption • Direct interface with TTL levels • Inputs accept voltages up to 5.
5 V • High-impedance when VCC = 0 V • Bus hold on all data inputs (74LVCH244A only) • Complies with JEDEC standard: • JESD8-7A (1.
65 V to 1.
95 V) • JESD8-5A (2.
3 V to 2.
7 V) • JESD8-C/JESD36 (2.
7 V to 3.
6 V) • ESD protection: • HBM JESD22-A114F exceeds 2000 V • MM JESD22-A115B exceeds 200 V • CDM JESD22-C101E exceeds 1000 V • Specified from -40 °C to +85 °C and -40 °C to +125 °C Nexperia 74LVC244A; 74LVCH244A Octal buffer/line driver; 3-state 3.
