description

These monolithic, positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic with a direct clear () input. Information at the data (D) inputs meeting setup time requirements is transferred to 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 (CLK) input is at either the high or low level, the D-input signal has no effect at the output.

The SN54F175 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74F175 is characterized for operation from 0°C to 70°C.
