Options for eight receive and four transmit channels are also available in a compact, cost effective 7mm x 7mm QFN package footprint.
Key Features
- HI-3225 and HI-3226 utilize external line receivers, for example Holt’s octal HI-8458 family
- Transmit outputs interface directly to external HI-8592, HI-8596, or integrated lightning protected HI-8597 ARINC 429 line drivers
- All parts use a 40 MHz 4-wire SPI (Serial Peripheral
