SN74HCT573DW Description

Short technical summary and product information.

The SN74HCT573DW is a D-type transparent latch containing eight independent latches with tri-state outputs. It is part of Texas Instruments' 74HCT logic family, combining TTL-compatible CMOS inputs with high-speed operation. Operating from a 4.5V to 5.5V supply, it draws a maximum supply current of only 80 µA. Each latch has an input current of 1 µA max and the typical propagation delay is 21 ns. The outputs can be placed in a high-impedance state, allowing bus-oriented applications. The device is housed in a 20-pin SOIC package and is specified for the industrial temperature range of -40°C to 85°C.
