74ALVC244

Octal buffer/line driver; 3-state

Rev. 6 — 11 July 2023

Product data sheet

1. General description

The 74ALVC244 is an 8-bit buffer/line driver with 3-state outputs. The device can be used as

two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE),

each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a

high-impedance OFF-state.

Schmitt trigger action on all inputs makes the device tolerant of slow rise and fall times.

This device is fully specified for partial power down applications using I_OFF. The I_OFFcircuitry

disables the output, preventing the potentially damaging backflow current through the device when

it is powered down.

2. Features and benefits

•

Wide supply voltage range from 1.65 V to 3.6 V

•

CMOS low power dissipation

Overvoltage tolerant inputs to 3.6 V

Direct interface with TTL levels

I_OFFcircuitry provides partial Power-down mode operation

Latch-up performance exceeds 250 mA per JESD78 Class II.A

Complies with JEDEC standards:

•

JESD8-7 (1.65 V to 1.95 V)

JESD8-5 (2.3 V to 2.7 V)

JESD8C/JESD36 (2.7 V to 3.6 V)

•

ESD protection:

•

HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

•

Multiple package options

Specified from -40 °C to +85 °C and from -40 °C to +125 °C
