SN74HCT273DWR TI Flip Flops

The SN74HCT273 is an octal D-type flip-flop with positive-edge triggering and master reset, featuring 3-state outputs for bus-oriented applications. It operates from 4.5V to 5.5V supply with TTL-compatible input thresholds, enabling direct interfacing with TTL logic while providing CMOS output levels. The device includes a master reset (MR) that asynchronously clears all flip-flops and a common clock (CLK). 3-state outputs are controlled by output enable (OE) for bus sharing. High drive capability supports bus driving without external components. Propagation delay is 18ns typical. Selection is ideal for 5V mixed TTL/CMOS systems requiring octal data storage. Applications include memory address registers, data storage for microprocessor systems, state registers, and temporary data buffering in industrial controls.
