Overview
The M74HC595YRM13TR is a high-speed CMOS 8-bit shift register with output latches, produced by STMicroelectronics. This device is fabricated using silicon gate C2MOS technology and is designed for a wide range of applications requiring serial-to-parallel data conversion. It features an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register, with 8 three-state outputs. The device includes separate clocks for both the shift register and the storage register, along with direct overriding clear, serial input, and serial output pins for cascading. It is pin and function compatible with the 74 series 595 and offers high noise immunity and balanced propagation delays.
