Mil-Std-1553 Products NHI-1500 Series +15V Dual Transceivers
Features/Applications:
Very Low Standby Power Low Thermal Resistance Totally Isolated Channels Short Circuit Proof Superior Noise Performance Screened to Mil-PRF-38534
Description:
The NHI +15V dual transceivers are available in 1.900" x .780", 36 pin plug-in and flatpack packages. Each receiver converts the 1553 bus bi-phase data to complementary RX and RX_L TTL digital outputs for use by the manchester decoder. The device provides independent receiver enables for each channel. Devices are available with receiver outputs normally HIGH or LOW during standby mode for compatibility with industry standard decoders. The transmitters will output bi-phase manchester to the coupling transformer when the TX and TX_L inputs are driven by complementary TTL digital data. The device provides an independent transmitter inhibit TXINH for each channel.

Transformer Requirements:
The NHI-1500 requires a transformer with a turns ratio of 1.40:1.00 for Direct Coupling, and a turns ratio of 2.00:1.00 for Transformer Coupling to the Mil-Std-1553 Bus. Technitrol part number Q1553-2 or equivalent is recommended. The center tap on the transceiver side of the isolation transformer must be grounded.
