The CD54AC241F3A is a high-reliability, dual-channel non-inverting buffer from Harris Corporation, part of the CD54AC CMOS logic family. It features 3-State outputs and operates over a wide voltage range of 1.5V to 5.5V, providing design flexibility for various logic levels. With 24mA source and sink capability, it can drive moderate loads effectively. The device is packaged in a 20-pin ceramic CDIP, designed for extreme temperature environments from -55°C to 125°C. This buffer is well-suited for military, aerospace, and industrial applications where reliability is paramount.
- Extreme Temperature Range (-55°C to 125°C): Guarantees operation in the harshest environments, ideal for military and aerospace.
- Wide 1.5V to 5.5V Supply: Supports both low-voltage and standard 5V logic, offering maximum design flexibility.
- Ceramic CDIP Package: Provides superior thermal conductivity and hermetic sealing for high-reliability applications.
- 3-State Outputs: Enables bus sharing and isolation, critical for redundant system architectures.
Low-Voltage Logic Interfacing
Use the CD54AC241F3A in battery-powered devices operating at 1.8V or 2.5V. Its wide 1.5V to 5.5V range allows seamless interfacing with both low-voltage microcontrollers and legacy 5V peripherals.
Military and Aerospace Electronics
The -55°C to 125°C temperature range and ceramic CDIP package make it ideal for military avionics, satellite systems, and other high-reliability applications requiring extreme temperature tolerance.
Signal Buffering for Sensors
Buffer weak sensor signals in industrial measurement systems. The 24mA output drive can strengthen signals for transmission over longer cables without degradation.
Bus Isolation in Redundant Systems
Implement bus isolation in redundant control systems. The 3-State outputs allow individual boards to be disconnected from the main bus for maintenance or fault isolation.
Mixed-Voltage System Design
Bridge 3.3V and 5V logic domains in mixed-voltage systems. The wide supply range and CMOS inputs provide high noise immunity and low power consumption.
Space-Constrained High-Reliability Designs
Use in compact, high-reliability modules where through-hole ceramic packaging is preferred for its thermal and mechanical robustness.
