For Use With External Transceivers
“Transceiverless Mode”
TXINH_OUT_B (O) These two signals
MUST be directly
connected for
normal “Built-In”
transceiver
operation.
L11
N/A
These two signals MUST be separated for
“Transceiverless” operation.
Transmitter inhibit inputs for Channel B of external
MIL-STD-1553 transmitters. To enable transmission on
Channel B, this input must be connected to logic “0”.
To force a shutdown of Channel B, a value of logic “1”
should be applied to the respective TX_INH input.
Digital transmit inhibit outputs. Connect to
TX_INH_OUT inputs of an external MIL-STD-1553
transceiver. Asserted high to inhibit when not trans-
mitting on the respective bus.

RXDATA_IN_A (I) These two signals
MUST be directly
connected for
normal “Built-In”
transceiver
operation.
