ON Semiconductor 74HC595AG 8-Bit Shift Register

The 74HC595AG is a high-performance, 8-bit serial-in/parallel-out shift register designed by ON Semiconductor. This integrated circuit (IC) is part of the 74HC series, known for their compatibility with CMOS and TTL logic levels. The 74HC595AG is particularly useful in expanding the output ports of microcontrollers with its cascading capability, making it an ideal choice for applications requiring additional output lines.

Key Features:

• Shift Register Type: Serial-in, parallel-out (SIPO)
• Output Type: 3-State outputs
• Number of Bits: 8 bits
• Logic Family: HC
• Operating Voltage Range: 2V to 6V
• Maximum Clock Frequency: 100 MHz at 6V
• Output Current: -35 mA / +35 mA
• Package: SOIC-16

Functional Description:

The 74HC595AG features an 8-bit shift register and an 8-bit D-type storage register. Data is shifted into the shift register on the rising edge of the clock signal. The shift register is then latched into the storage register on a separate clock input, often referred to as the register clock (RCLK). Once latched, the data in the storage register is available at the outputs in parallel form. The outputs can be placed in a high-impedance state, allowing for multiple registers to be connected in parallel and controlled by a single microcontroller pin.

Applications:

The versatility of the 74HC595AG makes it suitable for a wide range of applications, including:

• LED displays and LED matrices
• Digital control circuits
• Signal processing
• Serial-to-parallel data conversion
• Interface circuitry
• Input/output (I/O) expansion

Quality and Reliability:

ON Semiconductor is committed to the highest standards of quality and reliability. The 74HC595AG is manufactured with this commitment in mind, ensuring consistent performance and durability for your electronic projects and commercial applications.
