Frequently Asked Questions
What is the maximum clock frequency of the SN74HC595DBR?
The SN74HC595DBR supports a maximum clock frequency of 25MHz at nominal supply voltage with a 150pF load capacitance, making it suitable for high-speed serial data transfer and fast display refresh applications in the HC/UH logic family.
How can I cascade multiple SN74HC595DBR devices to expand output pins?
The SN74HC595DBR includes an unregistered serial shift-right output (QH') pin that connects directly to the serial data input (SER) of the next device in the chain. This allows unlimited cascading of multiple 8-bit shift registers using only 3 microcontroller pins: clock, data, and latch.
What package type is the SN74HC595DBR and what does 'DBR' suffix mean?
The SN74HC595DBR comes in a 16-pin Small Outline (SOIC) package, classified as R-PDSO-G16 per JESD-30. The 'D' suffix denotes the SOIC package, and 'BR' indicates it is supplied on tape and reel in quantities of 3000 units per reel, ideal for automated SMT assembly.
Is the SN74HC595DBR RoHS compliant and lead-free?
Yes, the SN74HC595DBR is fully RoHS compliant and lead-free, as indicated by its Pbfree Code 'Yes' and JESD-609 Code 'e4'. It meets all international environmental regulations for hazardous substances, making it suitable for consumer and industrial electronics.
What are common alternatives to the SN74HC595DBR?
Common pin-compatible alternatives include the SN74HC595N (DIP package), SN74HC595PW (TSSOP package), and the 74HC595 from other manufacturers such as NXP (74HC595D) and ON Semiconductor (MC74HC595ADR2G). All share the same 8-bit serial-in parallel-out shift register function with 3-state outputs.
