74HC244; 74HCT244

Octal buffer/line driver; 3-state

Rev. 7 — 27 July 2021

Product data sheet

1. General description

The 74HC244; 74HCT244 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. Inputs include clamp diodes that enable the use of current limiting

resistors to interface inputs to voltages in excess of V_CC

2. Features and benefits

•

Wide supply voltage range from 2.0 to 6.0 V

•

CMOS low power dissipation

High noise immunity

Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Input levels:

•

For 74HC244: CMOS level

For 74HCT244: TTL level

•

Octal bus interface

Non-inverting 3-state outputs

Complies with JEDEC standards:

•

JESD8C (2.7 V to 3.6 V)

JESD7A (2.0 V to 6.0 V)

•

ESD protection:

•

HBM JESD22-A114F exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

•

Multiple package options

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