Frequently Asked Questions
How does the CD4099BM function as a 1-of-8 demultiplexer in an output expansion circuit?
The CD4099BM uses a 3-bit address input to select one of 8 output latches, storing a logic level from a single data input line into the addressed latch. This demultiplexing function allows a microcontroller to control 8 independent output states using only 4 I/O pins (3 address + 1 data), reducing GPIO usage in relay or LED driver applications.
What supply voltage range does the CD4099BM support and which logic families can directly drive it?
The CD4099BM operates from 3V to 18V supply voltage, covering TTL-compatible 5V systems, CMOS 3.3V microcontrollers, and high-voltage 12V or 15V industrial logic families. This wide range eliminates level-shifting circuitry in mixed-voltage systems and makes the device backward-compatible with legacy 4000-series CMOS designs.
What output current limitation should be observed when driving loads from the CD4099BM?
The CD4099BM has a maximum output low current (IOL) of 2.4mA per channel. This limits direct LED or relay driving without a buffer stage; for loads requiring more than 2.4mA, a transistor or dedicated driver IC such as a ULN2003 should be inserted between the CD4099BM output and the load to prevent output stage saturation and voltage level degradation.
What is the SOIC-16 package footprint for the CD4099BM and is it RoHS compliant?
The CD4099BM is housed in a 16-pin SOIC (SOP-16) package with 1.27mm pin pitch, occupying approximately 9.9mm x 3.9mm on the PCB. The JESD-609 Code e4 marking confirms lead-free, RoHS-compliant finish, satisfying EU and China environmental compliance requirements for new product designs.
