1. General description
The 74AHC273-Q100; 74AHCT273-Q100 is a high-speed Si-gate CMOS device and is
pin compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with
JEDEC standard No. 7-A.
The 74AHC273-Q100; 74AHCT273-Q100 has eight edge-triggered, D-type flip-flops with
individual D inputs and Q outputs.
The common clock (CP) and master reset (MR
) inputs, load and reset (clear) all flip-flops
simultaneously. The state of each D input, one set-up time before the LOW-to-HIGH clock
transition, is transferred to the corresponding output (Qn) of the flip-flop.
All outputs are forced LOW, independent of clock or data inputs, by a LOW on the MR
input.
The device is useful for applications where only the true output is required and the clock
and master reset are common to all storage elements.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
