ON Semiconductor MC74VHC595DTR2G
The ON Semiconductor MC74VHC595DTR2G is a high-performance, 8-bit shift register with output latches that integrates advanced silicon-gate CMOS technology. Designed for a wide range of applications, this device offers a compact and efficient solution for serial-to-parallel data conversion and is particularly well-suited for use in microprocessor or microcontroller-based systems where the expansion of I/O ports is required.
Featuring an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register, the MC74VHC595DTR2G boasts high-speed operation with shift frequencies up to 100 MHz. The storage register has 8 parallel outputs, enabling the user to convert serial input data to parallel output format, thereby increasing the number of available output ports without the need for additional microprocessor pins.
The device operates over a wide voltage range from 2.0V to 5.5V, ensuring compatibility with low-voltage applications while maintaining the ability to interface with standard 5V logic levels. This flexibility makes it an ideal choice for interfacing with both modern low-power microprocessors and traditional 5V systems.
Key features of the MC74VHC595DTR2G include:
- 8-bit serial input to parallel output conversion
- High-speed operation with shift clock frequency up to 100 MHz
- 2.0V to 5.5V operating voltage range for broad compatibility
