74AHC126; 74AHCT126
Quad buffer/line driver; 3-state
The 74AHC126; 74AHCT126 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). A LOW 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.
Features and benefits
Balanced propagation delays
All inputs have Schmitt-trigger action
Inputs accept voltages higher than VCC
Input levels:
For 74AHC126: CMOS level
For 74AHCT126: TTL level
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Multiple package options
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
