Product data sheet
1. General description
The 74AHC244-Q100; 74AHCT244-Q100 is a high-speed Si-gate CMOS device.
The 74AHC244-Q100; 74AHCT244-Q100 has octal non-inverting buffer/line drivers with
3-state outputs. The 3-state outputs are controlled by the output enable inputs (nOE). A
HIGH on nOE causes the outputs to assume a high-impedance OFF-state.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
2. Features and benefits
Automotive product qualification in accordance with AEC-Q100 (Grade 1)
Specified from 40 C to +85 C and from 40 C to +125 C
Balanced propagation delays
All inputs have a Schmitt trigger action
Inputs accept voltages higher than VCC
For 74AHC244-Q100 only: operates with CMOS input levels
For 74AHCT244-Q100 only: operates with TTL input levels
ESD protection:
MIL-STD-883, method 3015 exceeds 2000 V
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V (C = 200 pf, R = 0 )
Multiple package options

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.

customer(s). Nexperia does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
