FK PACKAGE (TOP VIEW) 1Q CLR NC VCC 6Q 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. 4 3 2 1 20 19 18 5 17 6 16 7 15 8 14 9 10 11 12 13 6D 5D NC 5Q 4D 3Q GND NC CLK 4Q 1D 2D NC 2Q 3D The SN54HC174 is characterized for operation over the full military temperature range of –55°C to 125°C.
