SN74HC573ADBR Datasheet



These SN74HC573ADBR is octal transparent D-type latches 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. SN74HC573ADBR Features • Wide Operating Voltage Range of 2 V to 6 V• High-Current 3-State Outputs Drive Bus Lines Directly or Up To 15 LSTTL Loads• Low Power Consumption, 80-μA Max ICC• Typical tpd = 21 ns• ±6-mA Output Drive at 5 V• Low Input Current of 1 μA Max• Bus-Structured Pinout
