SN74HCT573

SN54HCT573, SN74HCT573 SCLS176G – JULY 2003 – REVISED JULY 2022 SNx4HCT573 Octal Transparent D-Type Latches With 3-State Outputs 1 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 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.
