IDT54/74FCT841A/B/C is a high-performance CMOS bus interface latch produced by Integrated Device Technology, Inc., which has the advantages of low current consumption, high reliability and high anti-interference.
The IDT54/74FCT841A/B/C latches provide buffered, 10‑bit wide bus interfacing with TTL‑compatible inputs and CMOS‑compatible outputs. They feature low input current, clamp diodes for ringing suppression, and are offered in radiation‑tolerant and radiation‑enhanced versions compliant with MIL‑STD‑883 Class B.
The datasheet lists absolute maximum ratings, electrical characteristics over the operating range, power‑supply requirements, and switching performance for both commercial (0 °C to +70 °C) and military (‑55 °C to +125 °C) temperature ranges. Ordering information includes DIP, CERDIP, CERPACK, leadless chip carrier, and small‑outline packages.
