• DM74LS175 Hex/Quad D-Type Flip-Flops with Clear

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 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 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.
s DM74LS174 contains six flip-flops with single-rail outputs
s DM74LS175 contains four flip-flops with double-rail outputs
s Buffered clock and direct clear inputs s Individual data input to each flip-flop s Applications include:

Buffer/storage registers Shift registers Pattern generators s Typical clock frequency 40 MHz s Typical power dissipation per flip-flop 14 mW

Note 1 The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation.
