CD74AC273M – TEXAS INSTRUMENTS

The CD74AC273M is an 8-bit D-type transparent latch with output registers, implemented in advanced CMOS technology. It features tri-state outputs, enabling bussing applications. Operating from a single 2V to 6V supply voltage (Vcc), it boasts a typical propagation delay of 4.5ns at 5V, making it suitable for high-speed designs. The device is specified to operate over a temperature range of -40°C to +85°C, making it suitable for industrial applications. Packaging is a space-saving 20-pin SOIC (Small Outline Integrated Circuit)._x000D_

Unlike simpler latches, the CD74AC273M’s tri-state outputs allow selective enabling/disabling of individual outputs onto a shared bus, crucial in memory addressing or data multiplexing. Its 8-bit architecture simplifies parallel data handling, reducing component count compared to cascading smaller latches. The transparent latch functionality allows for asynchronous data loading, simplifying timing constraints. The low power consumption inherent in CMOS technology, coupled with its speed, makes the CD74AC273M a strong choice for battery-powered or low-power applications needing fast data acquisition and storage. Its robust performance across a wide voltage range also enhances design flexibility and reliability. The SOIC package facilitates surface mount assembly, further enhancing its suitability for modern PCB designs.
