STMicroelectronics M74HC595YTTR 8-bit Shift Registers

The M74HC595YTTR is a high-performance CMOS 8-bit shift register with output latches from the reputable semiconductor manufacturer, STMicroelectronics. This integrated circuit is designed to deliver the reliability and functionality needed for a wide array of digital applications, particularly where the expansion of a microcontroller's I/O ports is required.

The device features an 8-bit serial-in, parallel-out shift register that allows the system to convert serial data into parallel data. This is particularly useful in applications where there is a need to interface with several output devices while minimizing the use of microcontroller pins. The shift register is followed by an 8-bit D-type storage register with 3-state outputs.

The M74HC595YTTR operates with a supply voltage ranging from 2V to 6V, making it compatible with TTL levels and suitable for use in systems that require low power consumption. Its high-speed performance is guaranteed at a clock frequency of up to 100 MHz when operating at 6V.

The device is equipped with a serial input (DS), a clock input (SHCP), an output enable input (OE), a latch enable input (STCP), and a clear input (MR) for the shift register. This allows for flexible control of the data input and output operations. Additionally, the shift register has a direct clear input, which can be used to reset the internal registers to a low state.

One of the key features of the M74HC595YTTR is its cascading capability. Multiple devices can be connected in series, which allows for the extension of the shift register length without the need for additional control lines. This makes it an ideal choice for applications requiring the control of a large number of outputs, such as LED displays, digital panels, and other signaling interfaces.

The device is offered in a compact TSSOP16 package, which is optimized for space-constrained applications. Its small form factor and the ability to operate over a wide temperature range from -55°C to +125°C make it suitable for industrial and automotive environments.

In summary, the M74HC595YTTR from STMicroelectronics is a versatile and efficient solution for digital systems requiring an 8-bit shift register with high-speed performance and low power consumption.
