54H20DM/B

Overview

The 54H20DM/B is a NAND gate integrated circuit belonging to the H series. It features three independent functions, each with three inputs. The device utilizes TTL logic technology and is housed in a ceramic dual in-line package (CDIP) with 14 pins. The physical dimensions of the package are 19.43 mm in length. It operates within a temperature range of -55 °C to 125 °C. The propagation delay is specified as 15 ns. The component is lead-free and RoHS compliant.

Feature Summary

• Provides three independent three-input NAND logic functions
• Constructed using TTL technology for reliable digital switching
• Encapsulated in a hermetically sealed ceramic DIP housing

Applications

• Digital logic circuit design requiring NAND operations
• Industrial control systems operating in extreme temperatures
• Military or aerospace electronic assemblies

Procurement Notes

Verify the specific lot traceability and manufacturing date code upon receipt. Confirm that the ceramic package integrity remains intact without cracks. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Cross-reference the marking codes against official manufacturer documentation to authenticate the source.

Selection Notes

Select this component when high-temperature stability and hermetic sealing are required. The ceramic construction offers superior protection against environmental factors compared to plastic packages. Consider the 15 ns propagation delay for timing constraints in the target circuit design.
