description

Thesedevicesarepositive-edge-triggeredD-type

flip-flops with a direct clear (CLR) input.

Information at the data (D) inputs meeting the setup time requirements is transferred to the Q 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 pulse. When CLK is at either the high or low level, the

D input has no effect at the output.

The SN54AHCT273 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74AHCT273 is characterized for operation from –40°C to 85 °C.
