Hex Quad D Flip-Flops with Clear
General Description
These positive-edge triggered flip-flops utilize TTL circuitry
to implement D-type flip-flop logic All have a direct clear
input and the quad (175) version features complementary
outputs from each flip-flop
Information at the D inputs meeting the setup and hold time
requirements is transferred to the Q outputs on the positive-
going edge of the clock pulse Clock triggering occurs at a
particular voltage level and is not directly related to the tran-
sition time of the positive-going pulse When the clock input
is at either the high or low level the D input signal has no
effect at the output
