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) versions feature complementary
outputs from each flip-flop
Information at the D inputs meeting the setup time require-
ments is transferred to the Q outputs on the positive-going
edge of the clock pulse Clock triggering occurs at a particu-
lar voltage level and is not directly related to the transition
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 LS174 contains six flip-flops with single-rail outputs
Y LS175 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 14 mW
Y Alternate Military Aerospace device (54LS174
54LS175) is available Contact a National Semiconduc-
tor Sales Office Distributor for specifications
