Key Features
- 8-bit serial-to-parallel shift register with independent output register for glitch-free operation
- 3-state output enables direct bus connection and multiple device cascading without additional logic
- 25MHz maximum clock frequency with low-power HC/UH CMOS technology for high-speed applications
- 8mA output drive current (I_OL) supports driving multiple standard logic inputs simultaneously
- Serial output pin allows cascading multiple SN74HC595 devices to expand to 16, 24, or more parallel outputs
Applications
The SN74HC595DT is widely used in microcontroller I/O expansion applications, where a single SPI or bit-banged serial interface can drive 8 or more output signals such as LEDs, relays, or display segments. It is commonly found in LED matrix displays, 7-segment digit drivers, and industrial control panels requiring port expansion. The device is also used in communication interfaces, automotive electronics, and embedded systems where minimizing GPIO pin count while maximizing output capacity is essential.

Frequently Asked Questions
What is the maximum clock frequency of the SN74HC595DT?
The SN74HC595DT supports a maximum shift register clock frequency of 25MHz at nominal supply voltage. This high-speed operation makes it suitable for fast serial-to-parallel data conversion in microcontroller interfaces, LED drivers, and other applications requiring rapid output updates.
How many SN74HC595DT devices can be cascaded together?
Multiple SN74HC595DT devices can be cascaded indefinitely by connecting the serial output (Q_H') of one device to the serial input (SER) of the next. This allows expansion from 8 outputs to 16, 24, 32 or more parallel outputs while using only 3 microcontroller pins (data, clock, latch), making it ideal for large LED arrays and display systems.
What package type and pin count does the SN74HC595DT use?
The SN74HC595DT comes in a 16-pin Small Outline (SOIC) surface-mount package with a JESD-30 code of R-PDSO-G16. The compact SMD package with 150pF load capacitance tolerance is suitable for automated PCB assembly and space-constrained designs in consumer electronics and industrial control boards.
What is the difference between the shift register clock and the storage register clock in the SN74HC595DT?
The SN74HC595DT has two separate clocks: SRCLK (shift register clock) shifts data serially into the 8-bit shift register on each rising edge, while RCLK (storage/latch clock) transfers the shift register contents to the parallel output register simultaneously on a rising edge. This dual-clock architecture allows new data to be loaded into the shift register without disturbing the current output state, enabling glitch-free output updates.
