74AHC125; 74AHCT125
Quad buffer/line driver; 3-state
The 74AHC125; 74AHCT125 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). 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.
Features and benefits
Wide supply voltage range from 2.0 V to 5.5 V
Overvoltage tolerant inputs to 5.5 V
High noise immunity
CMOS low power dissipation
Balanced propagation delays
All inputs have a Schmitt-trigger action
Input levels:
For 74AHC125: CMOS level
For 74AHCT125: TTL level
Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
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
