SN74HC541DWR – TEXAS INSTRUMENTS

The SN74HC541DWR is a high-speed CMOS 8-bit parallel-in/parallel-out shift register in a space-saving 16-pin WSON (Wide Small Outline N) package. It operates from a wide voltage range of 2V to 6V, offering significant design flexibility. This device features a single 8-bit data input, a serial data input (SI), a serial data output (SO), and eight parallel outputs (Q0-Q7). Data is shifted right on the rising edge of the clock (CLK) signal. The shift register’s operation is controlled by a single active-low load input (LD). When LD is low, parallel data is loaded directly into the register, overriding the serial input. When LD is high, serial data is shifted into the register._x000D_

The SN74HC541DWR’s high speed (typical propagation delay of 10ns at 5V) and low power consumption make it ideal for applications requiring high-throughput data manipulation within a limited power budget. Common uses include digital signal processing, data buffering, and temporary data storage in high-speed digital systems. Its CMOS technology ensures low power dissipation, making it suitable for battery-powered devices. The WSON package further enhances its suitability for space-constrained designs, offering a smaller footprint compared to traditional DIP packages. The device’s robust input and output characteristics provide excellent noise immunity.
