SN54ABT534 and SN74ABT534A are eight-bit edge-triggered D-type flip-flops with 3-state outputs. They feature state-of-the-art EPIC-II B BiCMOS design, significantly reducing power dissipation. They have latch-up performance exceeding 500 mA per JEDEC standard, output ground bounce less than 1 V, high-drive outputs, ESD protection exceeding 2000 V, and various package options.
The SN54ABT534 and SN74ABT534A are octal edge‑triggered D‑type flip‑flops that provide three‑state outputs. They are intended for driving highly capacitive loads, bus lines, and bidirectional I/O ports, with an output‑enable pin that can place the outputs in a high‑impedance state.
