Overview
The 54F32FMQB is a quad 2-input OR gate manufactured by National Semiconductor. It operates within a supply voltage range of 4.5V to 5.5V and features a low-level output current capability of 20mA. The device is housed in a 14-pin Ceramic Flat Pack (CFP) package, designated as CFP-14 or CFPQCCN14. It supports military-grade temperature ranges, functioning from -55°C to 125°C. This component belongs to the 54F series of logic devices.
Feature Summary
- Provides four independent 2-input OR logic functions
- Constructed using ceramic flat pack packaging for durability
- Designed for operation across extended military temperature ranges
Applications
- Military aerospace electronic systems
- Industrial control logic circuits
- High-reliability digital signal processing
Procurement Notes
Verify the specific ordering suffix FMQB against the manufacturer's official documentation to confirm the exact package type and material composition. Ensure compatibility with existing board layouts requiring ceramic flat pack footprints. Confirm that the 54F series specifications meet the required electrical standards for the intended application environment.
Selection Notes
Select this component when high noise immunity and robust performance are required in harsh environments. The ceramic construction offers superior thermal stability compared to plastic packages. Consider the 54F series speed-power trade-offs relative to other logic families if power consumption is a critical constraint in the system design.
Part Context
This part belongs to the 54F series, which denotes military-grade fast TTL-compatible CMOS logic. The 54 prefix indicates the extended temperature range suitable for defense and aerospace applications. National Semiconductor, now part of Texas Instruments, produced this line for high-reliability markets.
Replacement Considerations
Direct substitutes include other 54F32 variants with compatible pinouts such as 54F32J or 54F32N, provided the package style matches. Verify that any replacement maintains the same ceramic construction and voltage specifications to ensure environmental resilience.
