ON Semiconductor MC74HC595ADTR2 Shift Register

The MC74HC595ADTR2 is a high-performance, 8-bit shift register designed and manufactured by ON Semiconductor. This integrated circuit (IC) is part of the 74HC family, known for its high-speed CMOS technology, and it is a versatile component used in a wide range of digital applications. With its ability to convert serial input into parallel output, this shift register is an ideal choice for expanding the output ports of microcontrollers and for driving arrays of LEDs, displays, and other output devices.

The device features a serial input (SER), an output register with parallel 3-state outputs (Q0 to Q7), and a shift register with a serial output (Q7'). Data is shifted on the positive-going transitions of the shift register clock input (SHCP), and the data in the shift register is transferred to the output register on a positive-going transition of the storage register clock input (STCP). The output enable (OE) input can be used to place the eight outputs in either a high-impedance state or an active state, allowing for easy interface with other components.

One of the key benefits of the MC74HC595ADTR2 is its wide operating voltage range of 2V to 6V, which makes it compatible with TTL levels and suitable for use in systems that require low power consumption. The high current drive capability of ±35 mA at the outputs ensures that the device can directly drive LEDs and other output devices without the need for additional current-limiting resistors.

The MC74HC595ADTR2 comes in a TSSOP-16 package, providing a compact footprint for space-constrained applications. Its robust design ensures reliable operation over an extended temperature range of -55°C to +125°C, making it suitable for industrial and automotive environments where extreme conditions are common.

Overall, the MC74HC595ADTR2 from ON Semiconductor is a highly reliable and efficient solution for digital data processing and control. Its ease of use, combined with its ability to interface with various logic families, makes it a valuable component for designers looking to enhance their digital systems.
