Product data sheet
1. General description
The 74AHC244; 74AHCT244 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 are overvoltage tolerant. This feature allows the use of these
devices as translators in mixed voltage environments.
2. Features and benefits
Wide supply voltage range from 2.0 V to 5.5 V
Balanced propagation delays
All inputs have Schmitt-trigger action
Overvoltage tolerant inputs to 5.5 V
High noise immunity
CMOS low power dissipation
Input levels:
For 74AHC244: CMOS level
For 74AHCT244: TTL level
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101E exceeds 1000 V
Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
Multiple package options
