General description

   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

• ESD protection:

   • HBM JESD22-A114E exceeds 2000 V

   • MM JESD22-A115-A exceeds 200 V

   • CDM JESD22-C101C exceeds 1000 V

• Latch-up performance exceeds 100 mA per JESD 78 Class II Level A

• Multiple package options

• Specified from -40 °C to +85 °C and from -40 °C to +125 °C
