SN54HCT573 - OCTAL TRANSPARENT D-TYPE LATCHES

General Description

These octal transparent D-type latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads.

The ’HCT573 devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

Key Features

  • Operating voltage range of 4.5V to 5.5V.
  • High-Current 3-State Outputs Drive Bus Lines Directly or Up To 15 LSTTL Loads.
  • Low power consumption, 80-µA max ICC.
  • Typical tpd = 21ns.
  • ±6-mA output drive at 5V.
  • Low input current of 1µA max.
  • Inputs are TTL-Voltage compatible.
  • Bus-structured pinout 2.
