Overview
The National Semiconductor 4070BDM is a CMOS logic integrated circuit belonging to the 74HCT series. It contains four independent 2-input Exclusive-OR (XOR) gates and four independent 2-input NOR gates within a single package. The device utilizes complementary MOS technology to provide a wide power supply operating range, low power consumption, and high noise margins. It is housed in a 14-SOIC package with a width of 3.90mm.
Feature Summary
- Integrates four 2-input XOR gates for logical comparison operations
- Includes four 2-input NOR gates for standard logic functions
- CMOS construction ensures low power consumption and high noise immunity
Applications
- Digital logic circuits requiring exclusive-OR functionality
- Data comparison and parity generation systems
- General-purpose NOR gate applications in control logic
Procurement Notes
Verify the manufacturer designation carefully, as National Semiconductor assets are now part of Texas Instruments. Confirm that the specific suffix 'BDM' corresponds to the required 14-SOIC package and 74HCT series specifications. Ensure compatibility with your system's voltage levels and pinout requirements before procurement.
Selection Notes
Select this component when both XOR and NOR logic functions are needed in a compact form factor. The 74HCT series offers TTL-compatible inputs while maintaining CMOS output characteristics. Verify that the 14-SOIC package fits your PCB layout constraints and thermal management requirements.
Part Context
This part is part of the CD4070 family, which provides quad 2-input EXCLUSIVE-OR and NOR gates. The 4070BDM specifically denotes the National Semiconductor variant in a 14-SOIC package. It serves as a fundamental building block for complex digital logic designs requiring mixed gate types.
Replacement Considerations
Equivalent parts include the CD4070BM from National Semiconductor/TI. Other manufacturers may offer compatible quad XOR/NOR gates in SOIC packages, but verify pinout and electrical specifications match exactly.
