SN74HCT273PWR 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) input that asynchronously clears all flip-flops and a common clock (CLK) input. Each flip-flop has its own data (D) input, and outputs are true (non-inverting). The 3-state outputs are controlled by an output enable (OE) pin, allowing connection to shared bus systems. High drive capability supports bus driving without external components. Propagation delay is 18ns typical at 5V. Selection is ideal for 5V mixed TTL/CMOS systems requiring octal data storage with synchronous clocking and asynchronous reset. Applications include memory address registers, data storage for microprocessor systems, state registers for finite state machines, and temporary data buffering in industrial controls and telecommunications equipment.
