SN54HCT574

SN54HCT574, SN74HCT574 SCLS177G – MARCH 1984 – REVISED JULY 2022 SNx4HCT574 Octal Edge-Triggered D-Type Flip-Flips With 3-State Outputs 1 Features Operating voltage range of 4.5 V to 5.5 V High-current 3-state noninverting outputs drive bus lines directly or up to 15 LSTTL loads Low power consumption, 80-μA max ICC Typical tpd = 22 ns ±6-mA output drive at 5 V Low input current of 1 μA max Inputs are TTL-voltage compatible Bus-structured pinout 2 Description These octal edge-triggered D-type flip-flops feature 3-state outputs designed specifically for bus driving. The ’HCT574 devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
