SN74HC573AN Octal D-type latch, 3-state, 2 ... 6 V, DIL-20

Octal Transparent D-Type Latches With 3-State Outputs

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 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 - 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
