What are the key features of HCC4515BDG?
- Radiation-hardened ceramic glass-sealed DIL-24 package for space and high-reliability military logic applications
- 4-bit latch with integrated 4-to-16 line decoder combines two functions in a single 24-pin package for address decoding
- Inverted active-low outputs support direct interface to active-low memory enable and peripheral select lines in bus architectures
What is HCC4515BDG used for?
HCC4515BDG is designed for address decoding and memory bank selection in radiation-tolerant embedded systems such as satellite on-board computers, deep-space instrument controllers, and nuclear plant control electronics. Its latched input captures the address bus state and holds it while the 4-to-16 decoder activates one of 16 output lines, enabling glitch-free chip select generation. The ceramic DIL-24 package provides hermetic sealing for long-duration operation in harsh thermal and radiation environments.

Frequently Asked Questions
How does HCC4515BDG's latched input benefit address decoding in bus-based embedded systems?
The 4-bit input latch in HCC4515BDG captures the address bus state on a clock edge and holds it stable while the 4-to-16 decoder drives the appropriate output low. This prevents glitches on the 16 active-low outputs when the address bus transitions between cycles, ensuring clean chip select signals for memory ICs and peripherals. Without the latch, decoder outputs would momentarily activate multiple lines during bus transitions, potentially causing bus contention or spurious memory writes.
What radiation and environmental qualifications make HCC4515BDG suitable for space applications?
HCC4515BDG is housed in a ceramic glass-sealed DIL-24 package rated for total ionizing dose (TID) and thermal environments typically required in space-grade designs. The 4000-series CMOS process used by STMicroelectronics' rad-hard HCC family supports operation over extended temperature ranges beyond the standard 0°C to 70°C commercial range. The hermetic ceramic package protects the die against moisture ingress in vacuum environments, and the glass-sealed lid prevents outgassing that could contaminate sensitive optical or RF systems in satellite payloads.
Can HCC4515BDG replace CD4515 in a non-radiation-hardened industrial design, and what trade-offs apply?
HCC4515BDG is pin-compatible with standard CD4515 in the 24-pin DIP footprint and provides the same 4-to-16 decoder with latch function operating from 3 V to 18 V supply. It will work correctly in non-rad-hard industrial designs, but the ceramic package and radiation qualification add significant cost compared to plastic-packaged CD4515. For purely commercial or industrial applications without radiation requirements, CD4515BE or HEF4515B in a plastic package delivers identical logic function at lower cost per unit.
