General Description

The CD4 01 74B C con si sts o f si x po siti ve- ed ge trig ger ed D-

typ e f li p -fl o ps ; th e tr ue ou tpu t s fr om eac h f li p -f lo p a re ex ter -

nally available. The CD40175BC consists of four positive-

edge tri ggered D- type flip-fl ops; both the true an d compl e-

me nt outputs from each flip-flop are externally available.

All flip-flo ps are contr olled by a com mon clock and a com-

mon clear. Information at the D inputs meeting the set-up

time requirements is transferred to the Q outputs on the

positive-g oi ng ed ge of the clock pul s e. T he clea ri ng op er a-

tion, en abled 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 VDD and VSS.

Features

■Wide supply voltage range: 3V to 15V

■High noise immunity: 0.45 VDD (typ.)

■Low power TTL compatibility:

fan out of 2 driving 74L or 1 driving 74 LS

■Equivalent to MC14174B, MC14175B

■Equivalent to MM74C174, MM74C175

Ordering Code:

Devices also available in Tape and R eel. Speci fy by append ing the suffix let t er “X” to the ordering code.
