(TOP VIEW)

The ’ABT273 are 8-bit positive-edge-triggered

D-type flip-flops with a direct clear (CLR) input.

They are particularly suitable for implementing

buffer and storage registers, shift registers, and

pattern generators.

20 19

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

pulse. Clock triggering occurs at a particular

voltage level and is not directly related to the

transition time of the positive-going pulse. When

the clock (CLK) input is at either the high or low

level, the D input signal has no effect at the output.

The SN54ABT273 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74ABT273 is characterized for operation from –40°C to 85°C.
