National Semiconductor 54AC374
The ’AC/’ACT374 is a high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for each flip-flop and TRI-STATE outputs for bus-oriented applications.GENERAL DESCRIPTION
A buffered Clock (CP) and Output Enable (OE) are common to all flip-flops. Outputs source/sink 24 mA See ’273 for reset version See ’377 for clock enable version See ’373 for transparent latch version See ’574 for broadside pinout version See ’564 for broadside pinout version with inverted outputs n ’ACT374 has TTL-compatible inputs n Standard Military Drawing (SMD) — ’AC374: 5962-87694 — ’ACT374: 5962-87631 n n n n n nFEATURES
