MIL-STD-1553 3.3V Monolithic Dual Transceivers
DESCRIPTION
PIN CONFIGURATIONS
The HI-1573 and HI-1574 are low power
CMOS dual transceivers designed to meet the requirements of the MIL-STD-1553 specification.
The transmitter section of each bus takes complementary
CMOS / TTL Manchester II bi-phase data and converts it to differential
voltages suitable for driving the bus isolation transformer. Separate transmitter inhibit control signals are provided for each transmitter.
The receiver section of the each bus converts the 1553 bus bi-phase differential data to complementary
CMOS / TTL data suitable for input to a Manchester decoder. Each receiver has a separate enable input, which forces the receiver outputs to logic "0" (HI-1573) or logic “1” (HI1574).
To minimize the package size for this function, the transmitter outputs are internally connected to the receiver inputs, so that only two pins are required for connection to each coupling transformer. For designs requiring independent access to transmitter and receiver 1553 signals, please contact your Holt Sales representative.
