The 74HC573 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 outputs respond to the data (D) inputs. When LE is low, the outputs are latched to retain the data that was set up. 

Features:-

• Wide Operating Voltage Range from 2 V to 6 V

• Low Input Current: 1 µA (Maximum) 

• Bus-Structured Pinout

Application:-

• Buffer Registers 

• Bidirectional Bus Drivers 

• Working Registers
