NHi-15765/66 NHi-15LV765/66 +5v/+3.3v Monolithic 2Mbit-1553/1760 Transceivers
Features • Dual Transceiver • Totally Independent Channels • Single Power Supply • Short Circuit Tolerant • NHi Proprietary ASIC • Superior Noise Filter Description
The receivers convert Manchester II bi-phase data into complementary digital outputs. Each receiver has an independent digital enable. The transmitters convert complementary digital inputs into Manchester II bi-phase data. Each transmitter has an independent digital inhibit. A coupling transformer interfaces each transceiver to the Stub or Bus.
