SN54HC373-DIE (ACTIVE)

Octal Transparent D-Type Latch With 3-State Outputs

 

Description

This 8-bit latch features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The eight latches of the SN54HC373-DIE are transparent D-type latches. While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.

Features

  • Wide Operating Voltage Range
  • High-Current 3-State True Outputs Can
    Drive Up To 15 LSTTL Loads
  • Low Power Consumption
  • Typical tpd = 13 ns
  • Low Input Current
  • Full Parallel Access for Loading
