HI-1573, HI-1574
MIL-STD-1553
3.3V Monolithic Dual Transceivers
June 2013
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” (HI-
1574).
44 Pin Plastic 7mm x 7mm
Chip-scale package (QFN)
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.
