The S8T28F from Rochester Electronics is a single-channel non-inverting transceiver with 3-State outputs, designed for high-performance 5V systems. Operating from 4.5V to 5.5V, it delivers 10mA source and 48mA sink current, making it excellent for driving capacitive loads and backplanes. Packaged in a 16-CDIP ceramic package, it operates from -55°C to 125°C, ensuring reliability in military and industrial environments. Its bidirectional capability simplifies bus design.
- High Sink Current (48mA): Drives heavy bus loads and long cables with ease.
- 3-State Outputs: Enables bus sharing and isolation for multi-device systems.
- Ceramic Package: Provides superior thermal and mechanical reliability.
- Wide Temperature Range: Suitable for extreme environments.
High-Current Bus Driving
The S8T28F's 48mA sink capability makes it ideal for driving heavily loaded backplane buses in computer systems, ensuring signal integrity over long traces.
Bidirectional Data Transfer
Use it for bidirectional data lines between two subsystems. The 3-State outputs allow either side to drive the bus, with direction controlled by a direction pin.
Military Communication Systems
With its ceramic package and -55°C to 125°C range, it is suitable for military radios and radar systems requiring reliable data transfer in extreme conditions.
Industrial PLC I/O Modules
In programmable logic controllers, this transceiver can buffer communication between the CPU and I/O modules, handling the high current demands of industrial backplanes.
Memory Bus Isolation
Use it to isolate memory banks from the processor bus. The 3-State outputs allow disconnecting unused memory, reducing capacitive loading and improving speed.
Test and Measurement Equipment
For automated test systems, the S8T28F can route signals between test instruments and the device under test, providing robust drive for long cables.
