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

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

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 (LE) input is High, the Q outputs follow the data (D) inputs. When latch enable is taken Low, the Q outputs are latched at the levels of the D inputs one setup time prior to the High-to-Low transition.


  • 16-bit transparent latch
  • 5V I/O compatibile
  • 3-State buffers
  • Output capability: +64mA/-32mA
  • TTL input and output switching levels
  • Input and output interface capability to systems at 5V supply
  • Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs
  • Live insertion/extraction permitted
  • Power-up reset
  • Power-up 3-State
  • No bus current loading when output is tied to 5V bus
  • Latch-up protection exceeds 500mA per JEDEC Std 17
  • ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model
