Description

The 'LV174A devices are hex D-type flip-flops designed for 2-V to 5.5-V V_CC operation.

LV174A is monolithic positive-edge- triggered flip-flops with 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
pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going edge of the clock pulse. When the clock (CLR) input is at either the high or low level, the D-input signal of LV174A has no effect at the output.
