CD40174BC • CD40175BC
Hex D-Type Flip-Flop • Quad D-Type Flip-Flop
General Description
The CD40174BC consists of six positive-edge triggered D-
type flip-flops; the true outputs from each flip-flop are exter-
nally available. The CD40175BC consists of four positive-
edge triggered D-type flip-flops; both the true and comple-
ment outputs from each flip-flop are externally available.
All flip-flops are controlled by a common 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-going edge of the clock pulse. The clearing opera-
tion, enabled by a negative pulse at Clear input, 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
s Wide supply voltage range:
3V to 15V
s High noise immunity: 0.45 VDD (typ.)
s Low power TTL compatibility:
fan out of 2 driving 74L or 1 driving 74 LS
s Equivalent to MC14174B, MC14175B
s Equivalent to MM74C174, MM74C175
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
