SN54ACT574, SN74ACT574 OCTAL D-TYPE EDGE-TRIGGERED FLIP-FLOPS WITH 3-STATE OUTPUTS. Operates at 4.5V-5.5V, input voltages up to 5.5V, max tpd of 9 ns at 5 V, and TTL voltage compatible inputs.
The SN54ACT574 and SN74ACT574 devices are 8‑bit, edge‑triggered D‑type flip‑flops featuring three‑state outputs. They are intended for use as buffers, registers, I/O ports, bidirectional bus drivers and other logic functions, and can drive highly capacitive or low‑impedance loads.
The data sheet provides absolute maximum ratings, recommended operating conditions, detailed electrical characteristics, timing parameters, ordering information for multiple package types, mechanical drawings, and a package‑option addendum. It also includes an important notice on product availability and warranty.
The PDIP package is shown with 16 pins.
