74HCT273BQ-Q100集成电路（IC）的触发器规格书PDF中文资料

1. General description

The 74HC273-Q100; 74HCT273-Q100 is an octal positive-edge triggered D-type flip-flop. The

device features clock (CP) and master reset (MR) inputs. The outputs Qn will assume the

state of their corresponding Dn inputs that meet the set-up and hold time requirements on the

LOW-to-HIGH clock (CP) transition. A LOW on MR forces the outputs LOW independently of clock

and data inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to

interface inputs to voltages in excess of VCC.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
