- Wide supply voltage range of 3 V to 18 V for compatibility with diverse CMOS logic systems
- 16-pin DIP package for easy prototyping and through-hole PCB assembly
Applications
The CD4099BE is used in digital control systems where individual output bits must be independently addressable and latched without disturbing other outputs. It suits microcontroller I/O expansion, relay driver control panels, and programmable logic circuits operating on supply voltages from 3 V to 18 V. The 16-pin DIP package makes it a reliable choice for industrial and hobbyist through-hole board designs.

Frequently Asked Questions
How many addressable outputs does the CD4099BE provide and what supply voltage range does it support?
The CD4099BE provides 8 individually addressable latch outputs and operates across a supply voltage range of 3 V to 18 V. This wide voltage range makes it compatible with 5 V TTL-level and 12 V CMOS systems alike, simplifying interfacing in mixed-voltage industrial control and automation designs.
For which control panel or I/O expansion scenarios is CD4099BE the preferred choice?
The CD4099BE is preferred when a microcontroller needs to drive 8 independent latched outputs, such as relay coils, LED indicators, or solenoid drivers, without continuously refreshing all outputs. Its addressable latch architecture reduces the required GPIO pins to 3 address lines plus 1 data line, saving microcontroller I/O in 16-pin DIP form factor designs.
How does CD4099BE compare to a shift-register expander like the 74HC595 for output expansion?
Unlike the 74HC595 which requires clocking an 8-bit serial word to update any output, the CD4099BE allows updating a single one of 8 outputs using a 3-bit address and 1 data bit, eliminating the need to retransmit all 8 bits. This selective-write capability reduces SPI bus overhead at 5 V supply in time-critical embedded control loops.
