Octal buffer/line driver; 3-state
Rev. 6 — 27 September 2019
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
