CD40174BC • CD40175BC
Hex D-Type Flip-Flop • Quad D-Type Flip-Flop

General Description

The CD40174BC con sis ts o f six po si tive- ed ge tri g ger ed D­type fli p-flops; the true outputs from each fli p-flop are exter­nally available. The CD40175BC consists of four positive­edge triggered D-typ e flip-flo ps; both the tr ue and co mple­ment outputs from each flip-flop are externally available.

All flip-flops are controlled by a common clock a nd a com­mon clear. Information at the D inputs meeti ng the set-up
time requirements is transferred to the Q outputs on the
positive-going edge of the clock pulse. The clea ring op er a­tion, enabled by a ne gative pulse at Clear inpu t, clears all

Q outputs to logical “0” and Q

s (CD40175BC only) to logi-

cal “1”.
All inputs are protected from static discharge by diode

clamps to V

DD

and VSS.

Features

■ Wide supply voltage range: 3V to 15V
■ High noise immunity: 0.45 V

DD

(typ.)

■ Low power TTL compatibility:

Note 2: “Absolute Maximum Ratings” are those values beyond which the
safety of the device can not be guaranteed. T hey are not meant to imply
that the devices should be operated at these lim its. The tab les of “Recom ­mended Operating Conditions” and “Electrical Characteristics” provide con­ditions for actual dev ic e operation.
