description/ordering information
These devices are positive-edge-triggered octal
D-type flip-flops with an enable input. The ’HC377
devices are similar to the ’HC273 devices, but
feature a latched clock-enable (CLKEN) input
instead of a common clear.
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, if CLKEN is low. 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. These devices are designed to prevent
false clocking by transitions at CLKEN.
