Overview
The 54LS03/BCA is a quad 2-input NAND gate manufactured by Rochester Electronics. It utilizes Low-power Schottky (LS) TTL technology and features open-collector outputs. The component is housed in a ceramic dual in-line package with 14 pins. It is characterized for operation over the full military temperature range of -55°C to 125°C.
Feature Summary
- Contains four independent 2-input NAND logic gates
- Features open-collector output configuration
- Utilizes Low-power Schottky TTL technology
- Constructed in a hermetically sealed ceramic DIP-14 package
Applications
- Military aerospace systems requiring wide temperature tolerance
- Industrial control logic circuits
- General-purpose digital switching applications
Procurement Notes
Verify the specific suffix 'BCA' against official manufacturer documentation to confirm exact pinout, testing standards, and qualification level. Ensure the component meets required environmental specifications for the intended deployment environment before integration.
Selection Notes
Select this component when open-collector NAND functionality is required within a ruggedized ceramic package. The LS series offers a balance of speed and power consumption suitable for standard TTL logic families operating under extreme thermal conditions.
Part Context
Rochester Electronics provides lifecycle support for obsolete components. This part belongs to the SN54LS03 family, which is designed for high reliability. The ceramic construction ensures hermetic sealing, distinguishing it from plastic-packaged commercial variants.
Replacement Considerations
Compatible substitutes include the SN54LS03J or SN54LS03FK. Verify that replacement parts maintain the same open-collector output structure and military-grade temperature rating.
