The AM29C863/BKA is an inverting transceiver from AMD, designed for 5V systems requiring inverted data paths. It operates from 4.5V to 5.5V and provides 15mA source and 24mA sink current capability. The single-channel device is housed in a 24-pin ceramic flat pack (CFlatPack), ideal for space-limited military and aerospace applications. With a temperature range of -55°C to 125°C, it delivers reliable performance in extreme conditions.
- Inverting Function: Eliminates the need for external inverters, reducing component count and PCB area.
- Compact CFlatPack Package: Saves board space in high-density designs, ideal for avionics and satellites.
- High Sink Current (24mA): Can drive relays, LEDs, or low-impedance lines directly.
- Military Temperature Range: Guarantees operation in harsh environments from -55°C to 125°C.
Inverted Bus Communication
When system architecture requires inverted logic (e.g., active-low buses), this transceiver provides the necessary inversion without additional gates, saving board space.
Space-Constrained Avionics
The CFlatPack package is ideal for high-density PCB assemblies in avionics where height is limited, while the military temperature range ensures reliability.
Signal Polarity Correction
In systems where a sensor or peripheral outputs inverted data, this transceiver can correct the polarity while buffering the signal for long-distance transmission.
Legacy 5V Processor Interfacing
It provides a robust bidirectional interface for older 5V microprocessors that require inverted data paths, maintaining signal integrity.
Industrial Control with Active-Low Logic
Many industrial control systems use active-low signals for safety; this transceiver buffers and inverts these signals reliably over the full temperature range.
Test and Measurement Equipment
In ATE systems, the inverting function can be used to generate complementary test signals, while the high current drive supports long cable runs.
