The 'ABT273 are 8-bit positive-edge-triggered D-type flip-flops
with a direct clear ()
input. They are particularly suitable for implementing buffer and
storage registers, shift registers, and pattern generators.
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
