产品概览
The AIP74HC595D is an 8-bit serial-in/serial or parallel-out shift register with output latches and 3-state outputs. Compatible with the industry-standard 74HC595, it operates from 2V to 6V and achieves shift frequencies up to 55 MHz. Housed in a 16-pin SOIC package, it is widely used for I/O expansion in microcontroller-based systems.
