SN74LS273NSR TI Flip Flop | 20-SO | D-Type, Non-Inverting, 8-Bit

Product Overview

The SN74LS273NSR is a high-performance octal D-type flip-flop with clear, manufactured by Texas Instruments (TI). It features eight edge-triggered D-type flip-flops with individual D inputs and Q outputs, plus a common clock (CP) and a common asynchronous clear (CLR). The device is designed for general-purpose storage applications in digital systems, offering reliable operation over a wide voltage range. Packaged in a 20-pin SO (Small Outline) package, it is suitable for surface-mount technology (SMT) assembly, enabling compact and efficient PCB designs.
