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
Features
Y 174 contains six flip-flops with single-rail outputs
Y 175 contains four flip-flops with double-rail outputs
Y Buffered clock and direct clear inputs
Y Individual data input to each flip-flop
Y Applications include
Buffer storage registers
Shift registers
Pattern generators
Y Typical clock frequency 40 MHz
Y Typical power dissipation per flip-flop 38 mW
Y Alternate Military Aerospace device (54174 54175) is
available Contact a National Semiconductor Sales Of-
fice Distributor for specifications
