These octal positive-edge-triggered flip-flops utilize TTL
circuitry to implement D-type flip-flop logic with a direct-clear
(
) input.
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
transition time of the positive-going pulse. When CLK is at either
the high or low level, the D input signal has no effect at the
output.
The SN54ALS273 is characterized for operation over the full
military temperature range of -55°C to 125°C. The
SN74ALS273 is characterized for operation from 0°C to 70°C.
