What is CD40107BEE4 used for?
The CD40107BEE4 is used in open-drain bus interfacing applications where multiple NAND gate outputs are wire-OR'd together on a shared signal line, such as I2C-style control buses and alarm aggregation circuits. Its 89 mA sink current capability makes it suitable for directly driving indicator LEDs, optocouplers, and small relay coils without additional buffer transistors. The device also serves level-shifting applications in mixed-voltage systems where the pull-up resistor voltage differs from the driving logic supply.

Frequently Asked Questions
What is the maximum output sink current of the CD40107BEE4, and can it drive an LED directly without a transistor buffer?
The CD40107BEE4 can sink up to 89 mA per output, which comfortably exceeds the 10 mA to 20 mA typically required for standard indicator LEDs. This means a single gate output can directly drive an LED with only a series current-limiting resistor, eliminating the need for a buffer transistor and simplifying the schematic for panel indicator and status display circuits.
How does the open-drain output architecture of the CD40107BEE4 enable wired-OR bus implementations?
With open-drain outputs, the CD40107BEE4 can have multiple gate outputs connected to a single wire with a pull-up resistor to any desired voltage rail. The bus line is pulled low if any one of the connected outputs asserts, implementing a wired-OR function. This is the basis of I2C and similar protocols, allowing distributed control nodes to share a common signal line with pull-up resistors typically in the 1 kΩ to 10 kΩ range.
For a prototyping board design, what physical form factor does the CD40107BEE4 provide and how many pins does it have?
The CD40107BEE4 uses an 8-pin DIP (Dual In-Line Package) with 0.1-inch lead spacing, the most common through-hole format compatible with standard solderless breadboards, IC sockets, and prototype PCBs. The 8-pin DIP body is approximately 9.8 mm long and 6.35 mm wide, making it easy to handle during manual assembly and rework compared to surface-mount alternatives.
