74LVC244A; 74LVCH244A

Octal buffer/line driver; 3-state

Rev. 06 — 13 August 2009

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.

2. Features

I 5 V tolerant inputs/outputs for interfacing with 5 V logic

I Wide supply voltage range from 1.2 V to 3.6 V

I CMOS low-power consumption

I Direct interface with TTL levels

I Inputs accept voltages up to 5.5 V

I High-impedance when V_CC= 0 V

I Bus hold on all data inputs (74LVCH244A only)

I Complies with JEDEC standard no. 8-1A

I ESD protection:

N HBM JESD22-A114E exceeds 2000 V

N MM JESD22-A115-A exceeds 200 V

I Speciﬁed from −40 °C to +85 °C and −40 °C to +125 °C
