- 40 MHz maximum clock frequency in the LV logic family, supporting fast data shifting for high-throughput output control applications
- Daisy-chainable serial output (Q7S) for cascading multiple SN74LV595A devices to create wide parallel output buses from a single SPI interface
Applications
The SN74LV595ADRG3 is commonly used to expand the output capacity of microcontrollers by converting serial SPI data into parallel GPIO signals for driving LEDs, relays, and display segments. Its daisy-chain capability allows multiple devices to share the same SPI bus, enabling control of large LED matrices or multi-segment displays with minimal MCU pin usage. The device is also used in industrial control panels and embedded systems requiring efficient parallel output expansion from a limited serial interface.

Frequently Asked Questions
What does the SN74LV595ADRG3 do and how many outputs does it have?
The SN74LV595ADRG3 is an 8-bit serial-in parallel-out shift register that converts serial data input into 8 parallel output lines. It also includes a storage register with a separate output latch clock, allowing data to be shifted in without disturbing the outputs until the latch is triggered.
What is the maximum clock frequency supported by the SN74LV595ADRG3?
The SN74LV595ADRG3 supports a maximum clock frequency of 40 MHz at its nominal supply voltage with a 50 pF load capacitance, making it suitable for fast SPI-driven LED control, segment display drivers, and high-speed serial-to-parallel conversion in embedded designs.
How can multiple SN74LV595ADRG3 devices be connected together?
Multiple SN74LV595ADRG3 devices can be daisy-chained using the Q7S serial output of one device connected to the serial input (SER) of the next. This allows a single SPI port on a microcontroller to drive 16, 24, or more parallel outputs by cascading two, three, or more shift registers.
What package and logic family does the SN74LV595ADRG3 use?
The SN74LV595ADRG3 belongs to the LV (Low-Voltage) logic family and is housed in a 16-pin SOIC surface-mount package. The LV family operates over a wide voltage range, making it compatible with both 3.3 V and 5 V systems in mixed-voltage embedded designs.
What are typical applications for the SN74LV595ADRG3?
Typical applications include LED matrix drivers, 7-segment display controllers, relay output expanders, GPIO port expansion for microcontrollers, industrial control panels, and any embedded system where a limited number of SPI-capable pins must drive a large number of parallel output signals.
