Key Features
- Quad 2-input XOR gates: 4 fully independent exclusive-OR gates ideal for comparators, parity checkers, and arithmetic logic
- Ultra-wide supply voltage range: 3 V to 18 V enables use in 3.3 V, 5 V, 9 V, and 12 V systems without redesign
- CMOS 4000B series: low power, high noise immunity, and wide temperature range for industrial and legacy system support
- 14-pin DIP through-hole package for breadboard prototyping, socketed designs, and through-hole PCB assembly
Applications
The CD4030B-W is used in digital arithmetic circuits, parity generators/checkers, and bit comparison logic where the XOR truth table (output high only when inputs differ) is required. Its wide 3 V to 18 V supply range makes it particularly useful in legacy industrial systems, battery-powered equipment, and mixed-voltage designs where standard 5 V CMOS families are insufficient. XOR gates are also commonly used in programmable logic, pseudo-random number generators, and CRC (cyclic redundancy check) circuits for error detection in communication systems.

Frequently Asked Questions
What is the CD4030B-W and how many XOR gates does it contain?
The CD4030B-W is a quad 2-input exclusive-OR (XOR) gate IC from Texas Instruments, containing four independent XOR gates. Each gate outputs logic 1 only when its two inputs are at different logic levels. All four gates are independent and share only the VDD and GND supply pins in the 14-pin DIP package.
What supply voltage range does the CD4030B-W support?
The CD4030B-W supports an exceptionally wide supply voltage range of 3 V to 18 V, far exceeding standard CMOS (2 V to 6 V) and TTL logic families. This makes it compatible with 3.3 V, 5 V, 9 V, and 12 V digital systems, and useful in industrial applications, analog interface circuits, and battery-powered devices running from non-standard supply voltages.
What are common applications for XOR gates like the CD4030B-W?
XOR gates are used in digital arithmetic circuits (adders, subtractors), parity checkers, bit comparison logic, CRC generators, and LFSR-based pseudo-random number generators. In analog domains, XOR gates serve as phase detectors in PLL circuits. The quad configuration of the CD4030B-W allows implementing multi-bit XOR operations with a single component.
What package does the CD4030B-W use and what does the -W suffix mean?
The CD4030B-W is housed in a 14-pin DIP (Dual-In-Line Package) through-hole package. The -W suffix in Texas Instruments part numbering typically denotes the ceramic or military-grade/wide-temperature variant, offering enhanced reliability and extended temperature range compared to the commercial plastic DIP version. Verify the datasheet for exact specifications of this variant.
What are alternatives to the CD4030B-W?
Alternatives include the CD4070B for the same XOR function in a standard plastic DIP, the SN74HC86 for 2 V to 6 V high-speed CMOS operation, or the SN74HCT86 for TTL-input-compatible systems. For surface-mount designs, the SN74AHC86 in SOIC or TSSOP packages provides faster propagation at lower supply voltage with a modern package option.
