SN54HC563, SN74HC563 SCLS145E - DECEMBER 1982 - REVISED JULY 2022 SNx4HC563 Octal Transparent D-Type Lataches With 3-State Outputs 1 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 - Lowpower 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 2 Description These 8-bit transparent D-type latches feature 3state 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.
