These devices have a direct clear (CLR) input and feature complementary outputs from each flip-flop. 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 SN54LV175A is characterized for operation over the full military temperature range of 55C to 125C. The SN74LV175A is characterized for operation from 40C to 85C. FUNCTION TABLE
