4030 IC Quad 2-Input XOR Gate DIP-14 
The 4030 is a CMOS quad 2-input exclusive-OR (XOR) gate designed for general-purpose digital logic. Each of the four independent gates implements the XOR Boolean function, producing a high output when inputs differ. Built on a low-power CMOS process, the device offers wide supply-voltage flexibility and high noise immunity, making it suitable for battery-powered and industrial applications where power efficiency and stability are important.
Internally, the CD4030B combines complementary MOSFET structures to achieve rail-to-rail outputs and relatively low static current over a broad voltage range. The gates exhibit symmetrical switching thresholds and predictable timing behavior, which simplifies cascading multiple devices in larger logic networks. Standard logic connections and pinouts follow JEDEC conventions for 14-pin packages, allowing drop-in replacement in many legacy and modern circuit boards.
Available in multiple package options (PDIP, SOIC, SOP, TSSOP, CDIP), the CD4030B is offered in commercial and military-qualified versions. Its simplicity makes it an ideal building block for parity generation, conditional inversion, arithmetic logic circuits, and other combinational logic functions. Designers value the CD4030B for its robustness, predictable behaviour, and ease of integration into TTL- and CMOS-level systems. It supports a broad temperature range and standard soldering processes for reliable manufacturing worldwide.
