74HC244; 74HCT244

Octal buffer/line driver; 3-state

Rev. 4 — 24 September 2012

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

 Input levels:

 For 74HC244: CMOS level

 For 74HCT244: TTL level

 Octal bus interface

 Non-inverting 3-state outputs

 Complies with JEDEC standard no. 7 A

 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
