description

These octal positive-edge-triggered flip-flops

utilize TTL circuitry to implement D-type flip-flop

logic with a direct-clear (CLR) 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.
