NHi-1567/68 NHi-15LV67/68 NHi-15133/134 NHi-15LV133/134
+5v/+3.3v Monolithic Mil-Std-1553/1760 Transceivers
Features
Description
• Dual Transceiver
• Totally Independent Channels
• Single Power Supply
• Short Circuit Tolerant
• NHi Proprietary ASIC
• Superior Noise Filter
• Mac-Air compliant version also
available
• NHi-15133/134 has higher receiver
threshold
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.
