ON Semiconductor MC74HC595ADR2 - 8-Bit Shift Register with Output Latches

The MC74HC595ADR2 is a high-performance, 8-bit serial-in/parallel-out shift register with a storage register and 3-state outputs from ON Semiconductor. This versatile integrated circuit is designed to be used in a wide array of applications, ranging from microprocessor expansion and interface reduction to data control systems and signal processing.

Key Features:

• Shift Register Type: Serial to Parallel
• Number of Bits per Element: 8
• Output Type: 3-State
• Supply Voltage Range: 2V to 6V
• Operating Temperature Range: -55°C to +125°C
• Mounting Type: Surface Mount
• Package / Case: SOIC-16
• Logic Family: HC
• Logic Type: Shift Register

The device features a serial input (DS) and a serial standard output (Q7’) that enables cascading of multiple devices without the need for external circuitry. The shift register and storage register have separate clocks. Data is shifted on the positive-going transitions of the shift register clock (SHCP). The data in the storage register is transferred to the output buffer when the output enable (OE) input is high. A low on OE causes the outputs to assume a high-impedance OFF-state.

Operation of the MC74HC595ADR2 is straightforward: data is entered serially through the DS input and shifted out on the Q7’ output to the next device in the chain. This makes it possible to extend the data bus width using multiple MC74HC595ADR2 devices. The device also has a master reset (MR) input that immediately clears the entire shift register when taken high.

ON Semiconductor's MC74HC595ADR2 is a reliable and flexible solution for digital system designers looking to improve data handling efficiency. Its robust design ensures it can operate under harsh conditions, making it suitable for industrial, automotive, and consumer applications where high data integrity and reliability are essential.
