Thesedevicesarepositive-edge-triggeredD-type

flip-flops with a common enable input. The

’HCT273 are similar to the ’HCT377, but feature

a common clear enable (CLR) input instead of a

latched clock.

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 positive-going pulse. When CLK is at either

the high or low level, the D input has no effect at

the output. The circuits are designed to prevent

false clocking by transitions at CLR.

The SN54HCT273 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74HCT273 is characterized for operation from –40°C to 85°C.
