74LVC16373A; 74LVCH16373A

16-bit D-type transparent latch with 5 V tolerant inputs/outputs; 3-state

The 74LVC16373A and 74LVCH16373A are 16-bit D-type transparent latches with 3-state outputs. The devices can be used as two 8-bit transparent latches or a single 16-bit transparent latch. The devices feature two latch enables (1LE and 2LE) and two output enables (1OE and 2OE), each controlling 8-bits. When nLE 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 nLE is LOW the latches store the information that was present at the inputs a set-up time preceding the HIGH-to-LOW transition of nLE. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Operation of the nOE input does not affect the state of the latches. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

Bus hold on the data inputs eliminates the need for external pull-up resistors to hold unused inputs.

Features and benefits

  • Overvoltage tolerant inputs to 5.5 V
  • Wide supply voltage range from 1.2 V to 3.6 V
  • CMOS low power dissipation
  • MULTIBYTE flow-through standard pinout architecture

  • Direct interface with TTL levels
  • All data inputs have bus hold (74LVCH16373A only)
  • IOFF circuitry provides partial Power-down mode operation
  • Complies with JEDEC standards:
    • JESD8-7A (1.65 V to 1.95 V)
    • JESD8-5A (2.3 V to 2.7 V)
    • JESD8-C/JESD36 (2.7 V to 3.6 V)
  • ESD protection:
