description

These devices are positive-edge-triggered D-type flip-flops. The'HCT377 are similar to the 'HCT273 but feature a latched clock-enable() input insteadof a common clear.

Information at the data (D) inputs meeting the setup timerequirements is transferred to the Q outputs on the positive-goingedge of the clock (CLK) pulse if is low. Clock triggering occurs at a particular voltagelevel and is not directly related to the transition time of thepositive-going pulse. When CLK is at either the high or low level,the D input has no effect at the output. These devices are designedto prevent false clocking by transitions at.

The SN54HCT377 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74HCT377 is characterized for operation from -40°C to85°C.
