Information at the data (D) inputs meeting the
setup time requirements is transferred to the
outputs on the positive-going edge of the clock
NC – No internal connection
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.
