description
These monolithic, positive-edge-triggered flipflops utilize TTL circuitry to implement D-type flip-flop logic with a direct clear (CLR) 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.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: The input voltage ratings may be exceeded provided the input current ratings are observed.

VCC = 5.5 V, See Note 2 22.5 34 22.5 34 mA All typical values are at VCC = 5 V, TA = 25°C. § Not more than one output should be shorted at a time, and the duration of the short circuit should not exceed one second. NOTE 2: ICC is measured with outputs open with 4.5 V applied to all data inputs after a momentary ground followed by 4.5 V applied to CLK.
