description

The ’LV174A devices are hex D-type flip-flops

These devices are 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 (CLK) input is at either the high or

low level, the D-input signal has no effect at the output.

The SN54LV174A is characterized for operation over the full military temperature range of –55

°C to 125°C.

The SN74LV174A is characterized for operation from –40

°C to 85°C.
