description
These devices are positive-edge-triggered D-type
flip-flops. The ’HCT377 are similar to the ’HCT273
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.
The SN54HCT377 is characterized for operation over the full military temperature range of –55
°C to 125°C. The
SN74HCT377 is characterized for operation from –40
°C to 85°C.
