74AHC373

Octal D-type transparant latch; 3-state

The 74AHC373 is an octal D-type transparent latch with 3-state outputs. The device features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs enter the latches. In this condition the latches are transparent, a latch output will change each time its corresponding D-input changes. When LE is LOW the latches store the information that was present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the state of the latches. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

特性

  • Overvoltage tolerant inputs to 5.5 V

  • High noise immunity

  • CMOS low power dissipation

  • Balanced propagation delays

  • All inputs have a Schmitt-trigger action

  • Common 3-state output enable input

  • Inputs accepts voltages higher than VCC

  • 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

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