SN74LS273NSR Datasheet

Flip Flops


These monolithic, positive-edge-triggered flipflops utilize TTL circuitry to implement D-type flip-flop logic with a direct clear input. 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 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 ′273 and 10 milliwatts for the ′LS273( SN74LS273NSR ). SN74LS273NSR Features • Contains Eight Flip-Flops With Single-Rail Outputs• Buffered Clock and Direct Clear Inputs• Individual Data Input to Each Flip-Flop• Applications Include:- Buffer/Storage Registers- Shift Registers- Pattern Generators
