Hex D-type Flip-Flops (with Clear)
Description
This device contains 6 master-slave flip-flops with a common clock and common clear. Data on the D
input having the specified setup and hold times is transferred to the Q output on the low to high transition
of the clock input. The clear input when low, sets all outputs to a low state.
Features
High Speed Operation: t
pd
(Clock to Q) = 15 ns typ (C
L
= 50 pF)
High Output Current: Fanout of 10 LSTTL Loads
Wide Operating Voltage: V
CC
= 2 to 6 V
Low Input Current: 1 μA max
Low Quiescent Supply Current: I
CC
(static) = 4 μA max (Ta = 25°C)
