Overview
The M74HC595TTR is a high-speed CMOS 8-bit shift register with output latches (3-state) manufactured by STMicroelectronics. This device is fabricated using silicon gate C2MOS technology and features an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has 8 3-state outputs, and separate clocks are provided for both the shift register and the storage register. This component is designed for high-speed operations and low power dissipation, making it suitable for various applications.
