SN54HC573A Octal Transparent D-Type Latche

The SNx4HC573A devices are octal transparent D-type latches that feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. While the latch-enable (LE) input is high, the Q output.

Features

• Wide Operating Voltage Range from 2 V to 6 V
• High-Current 3-State Outputs Drive Bus Lines Directly up to 15 LSTTL Loads
• Low Power Consumption: 80-µA Maximum ICC
• Typical tpd = 21 ns
• ±6-mA Output Drive at 5 V
• Low Input Current: 1 µA (Maximum)
• Bus-Structured Pinout 2 Applications
• Buffer Registers
• Bidirectional Bus Drivers
• Working Registers 3 Description The SNx4HC573A devices are octal transparent D-type latches that feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing b.
