Key Features
- Quad 2-input XOR gate provides four independent exclusive-OR functions in a single 14-pin package for compact combinational logic designs
- Wide supply voltage range of 3V to 18V (CMOS 4000-series) supports operation across battery, 5V logic, and industrial 12V/15V power rails
- 14-pin ceramic DIP (CDIP) package offers enhanced reliability and temperature stability compared to plastic DIP for military and high-reliability applications
- XOR gate topology directly implements parity generation, binary addition, and controlled inversion functions without additional logic gates
Applications
The CD4070BF is used in digital logic designs requiring exclusive-OR operations such as parity generators, binary comparators, and arithmetic circuits. Its four XOR gates are commonly applied in encryption key mixing, CRC checksum circuits, and phase detection for digital communication systems. The wide 3V to 18V supply range makes it versatile for use in both low-power portable devices and industrial control systems with 12V or 15V logic levels.

Frequently Asked Questions
What logic function does the CD4070BF perform?
The CD4070BF implements the exclusive-OR (XOR) logic function. Each of its four gates outputs a logic high only when its two inputs differ — that is, one input is high and the other is low. When both inputs are the same (both high or both low), the output is logic low.
How many XOR gates are in the CD4070BF?
The CD4070BF contains four independent 2-input XOR gates in a single 14-pin package. Each gate has two dedicated input pins and one output pin, sharing only the VCC and GND supply pins. This quad configuration enables multi-bit XOR operations in a single device.
What supply voltage range does the CD4070BF support?
As a CMOS 4000-series device, the CD4070BF operates over a supply voltage range of 3V to 18V. This wide range allows direct use in 3.3V microcontroller systems, standard 5V TTL-compatible logic, and industrial 12V or 15V power environments without external voltage regulation.
What package does the CD4070BF use?
The CD4070BF comes in a 14-pin ceramic DIP (CDIP) package with JEDEC code R-GDIP-T14. The ceramic package provides superior temperature stability and moisture resistance compared to plastic DIP, making it preferred for military, aerospace, and industrial applications with extended reliability requirements.
What are common applications for the CD4070BF?
Common applications include parity bit generation, binary adder circuits, comparators, phase detectors, and controlled signal inversion. The XOR function is also fundamental to encryption algorithms and CRC error-detection circuits in serial communication interfaces, making the CD4070BF a versatile building block in digital systems.
