description
These devices are positive-edge-triggered D-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.
