What are the key features of CD4099BF3A?
- 8-bit addressable D-latch doubles as a 1-of-8 demultiplexer for output expansion with minimal pins
- Wide 3 V to 18 V supply range compatible with TTL, CMOS, and battery-powered 5 V systems
- 16-pin ceramic DIP package for high-reliability military and industrial applications
- Latched outputs retain state during address changes, preventing glitches on output lines
What is CD4099BF3A used for?
The CD4099BF3A is used in industrial control panels, legacy programmable logic systems, and 8-channel relay-driver interfaces where a 3-wire address bus must control 8 independent output lines independently. Its wide supply voltage range and ceramic DIP package make it especially useful in temperature-hardened or military-grade electronics where plastic packages are not acceptable, and in retrofit applications maintaining compatibility with existing 4000-series CMOS logic families.

Frequently Asked Questions
How does CD4099BF3A function as a 1-of-8 demultiplexer and what pins control address selection?
The CD4099BF3A uses a 3-bit address input (A0, A1, A2) to select one of 8 output latches, routing the state of the serial data input D to the addressed output while the remaining 7 outputs hold their previous states. The Write Enable pin controls when data is clocked in, implementing a complete 1-of-8 demultiplexer using only 5 control signals instead of 8 separate data lines.
What supply voltage range does CD4099BF3A support and what output current can it sink?
The CD4099BF3A operates from 3 V to 18 V supply voltage, supporting TTL-compatible 5 V, industrial 12 V, and CMOS 15 V systems from a single part number. Output sink current is 2.4 mA at 5 V supply and increases to approximately 10 mA at 18 V, sufficient to drive LED indicators and low-power relay coils directly without buffers.
Why would a ceramic DIP package be chosen for CD4099BF3A over a plastic SOIC version?
The ceramic DIP package of CD4099BF3A is hermetically sealed, providing moisture resistance suitable for military MIL-STD-883 qualification and operation across -55 °C to 125 °C extended temperature ranges where plastic packages can delaminate or absorb humidity. It is specified for applications in aerospace avionics, ground support equipment, and industrial systems requiring long-term reliability over a 20-year service life.
How does CD4099BF3A reduce wiring complexity in an 8-channel output expansion design?
Instead of requiring 8 separate GPIO lines from a microcontroller to drive 8 outputs, CD4099BF3A needs only 5 signals: a 3-bit address bus, one data line, and one write enable. This frees up 3 GPIO pins on the MCU and reduces PCB trace count from 8 to 5, making it valuable in pin-limited microcontrollers such as 8-pin PIC or ATtiny devices controlling 8 relay channels.
