16-bit transparent D-type latch; 3-state

The 74ALVT16373 is a high-performance BiCMOS product designed for VCC operation at 2.5 V or 3.3 V with I/O compatibility up to 5 V.

This device is a 16-bit transparent D-type latch with non-inverting 3-state bus compatible outputs. The device can be used as two 8-bit latches or one 16-bit latch. When latch enable (nLE) input is HIGH, the nQn outputs follow the date (nDn) inputs. When latch enable is taken LOW, the nQn outputs are latched at the levels of the D inputs one setup time prior to the HIGH-to-LOW transition.

  • Live insertion/extraction permitted
  • Power-up reset
  • Power-up 3-State
  • No bus current loading when output is tied to 5 V bus
  • Latch-up protection:
    • JESD 17: exceeds 500 mA
  • ESD protection:
    • MIL STD 883 method 3015: exceeds 2000 V
    • MM exceeds 200 V
