description

These circuits are positive-edge-triggered D-type

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

9 10 11 12 13

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 SN54AHC273 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74AHC273 is characterized for operation from –40°C to 85 °C.
