SN54HC174, SN74HC174 Hex D-Type Flip-Flops with Clear
These monolithic positive-edge-triggered D-type flip-flops have a direct clear (CLR) input.
Information at the data (D) inputs meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going edge of CLK. When CLK is at either the high or low level, the D input has no effect at the output.
The SN54HC174 is characterized for operation over the full military temperature range of –55°C to 125°C. The SN74HC174 is characterized for operation from –40°C to 85°C.
