The SNJ54ALS653FK is an inverting 8-bit transceiver from Texas Instruments, part of the 54ALS family. It operates at 5V (4.5V-5.5V) and offers both 3-state and open-collector outputs, providing flexibility in bus design. Packaged in a 28-pin CLCC, it is designed for military applications with a temperature range of -55°C to 125°C.
- Dual Output Types (3-State & Open Collector): Flexible for various bus architectures.
- Inverting Function: Useful for logic inversion in data paths.
- Compact CLCC Package: Saves space in high-density designs.
- Military Temperature Range: Reliable in extreme conditions.
Wired-OR Bus with 3-State Option
The combination of open-collector and 3-state outputs allows implementing wired-OR logic on one side and standard 3-state bus on the other.
Inverting Bus Transceiver
Use it to invert data signals while providing bidirectional transfer between two buses, useful in control logic.
Level Shifting with Pull-Ups
The open-collector outputs can be pulled up to different voltages, enabling level shifting in mixed-voltage systems.
High-Density Packaging
The 28-pin CLCC package saves board space in compact military and aerospace modules.
Interrupt and Status Lines
Open-collector outputs are ideal for shared interrupt lines where multiple devices can assert a signal.
Redundant System Interfaces
In fault-tolerant systems, the open-collector outputs allow for redundant connections without bus conflicts.
