Description

These SN74LS273 monolithic, positive-edge-triggered flipflops utilize TTL circuitry to implement D-type flip-flop logic with a direct clear input.

SN74LS273 Information at the 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 input is at either the high or low level, the D input signal has no effect ar the output.

These flip-flops SN74LS273 are guaranteed to respond to clock frequencies ranging form 0 to 30 megahertz while maximum clock frequency is typically 40 megahertz. Typical power dissipation is 39 milliwatts per flip-flop for the 4273 and 10 milliwatts for the 4LS273.
