HD74LS174 / HD74LS175

Hex / Quadruple D-type Flip-Flops (with clear)

REJ03D0451–0300

Rev.3.00

Jul.15.2005

These positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic. All have a direct

clear input, and the HD74LS175 features complementary outputs from each flip-flops. 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 outputs.
