74LVC244A; 74LVCH244A

Octal buffer/line driver; 3-state

Rev. 12 — 16 September 2021

Product data sheet

1. General description

The 74LVC244A; 74LVCH244A are 8-bit buffer/line drivers with 3-state outputs. The devices can

be used as two 4-bit buffers or one 8-bit buffer. Both devices 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. Inputs can be driven from either 3.3 V or 5 V devices. This feature

allows the use of these devices as translators in mixed 3.3 V and 5 V environments.

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_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 1.2 V to 3.6 V

•

CMOS low-power consumption

Direct interface with TTL levels

Overvoltage tolerant inputs to 5.5 V

I_OFFcircuitry provdes partial Power-down mode operation

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
