74HC174D-Q100集成电路（IC）的触发器规格书PDF中文资料

1. General description

The 74HC174-Q100; 74HCT174-Q100 are hex positive edge-triggered D-type flip-flops with

individual data inputs (Dn) and outputs (Qn). The common clock (CP) and master reset (MR)

inputs load and reset all flip-flops simultaneously. The D-input that meets the set-up and hold

time requirements on the LOW-to-HIGH clock transition is stored in the flip-flop and appears at

the Q output. A LOW on MR causes the flip-flops and outputs to be reset LOW. 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.
