FEATURES
DESCRIPTION
The HI-1569 is a low power CMOS dual transceiver
designed to meet the requirements of MIL-STD-1553
/1760 specifications.
The transmitter section of each channel takes
complementary CMOS / TTL digital input data and
converts it to bi-phase Manchester encoded 1553 signals
suitable for driving the bus isolation transformer. Separate
transmitter inhibit control signals are provided for each
transmitter.
The receiver section of each channel converts the 1553
bus bi-phase data to complementary CMOS / TTL data
suitable for inputting to a Manchester decoder. Each
receiver has a separate enable input which can be used to
force the output of the receiver to a logic 0.
! Compliant to MIL-STD-1553A & B,
MIL-STD-1760, ARINC 708A
! CMOS technology for low standby power
! Single 5V power supply
! Less than 1.0W maximum power dissipation
! Military processing options
! Industry standard 64-pin PQFP package

FUNCTIONAL DESCRIPTION
The HI-1569 data bus transceiver contains differential voltage source drivers and differential receivers. It is intended
for applications using a MIL-STD-1553 A/B data bus. The
device produces a trapezoidal output waveform during
transmission.
TRANSMITTER
Data input to the device’s transmitter section is from the
complementary CMOS /TTL inputs TXA/B and TXA/B.
The transmitter accepts Manchester II bi-phase data and
converts it to differential voltages on BUSA/B OUT and
BUSA/B OUT. The transceiver outputs are either direct or
transformer coupled to the MIL-STD-1553 data bus. Both
coupling methods produce a nominal voltage on the bus of
7.5 volts peak to peak.
The transmitter is automatically inhibited and placed in the
high impedance state when both TXA/B and TXA/B are either at a logic “1” or logic “0” simultaneously. A logic “1” applied to the TXINHA/B input will force the transmitter to the
high impedance state, regardless of the state of TXA/B and
TXA/B.
RECEIVER
The receiver accepts bi-phase differential data from the MILSTD-1553 bus through a direct or transformer coupled interface. The receiver’s differential input stage drives a filter and
threshold comparator that produces CMOS/TTL data at the
RXA/B and RXA/B output pins.
Each set of receiver outputs can be independently forced to a
logic "0" by setting RXENA or RXENB low.
MIL-STD-1553 BUS INTERFACE
A direct coupled interface (see Figure 2) uses a 1:2.5 ratio
isolation transformer and two 55 ohm isolation resistors
between the transformer and the bus.
In a transformer coupled interface (see Figure 3), the
transceiver is connected to a 1:1.79 isolation transformer
which in turn is connected to a 1:1.4 coupling transformer. The
transformer coupled method also requires two coupling
resistors equal to 75% of the bus characteristic impedence
(Zo) between the coupling transformer and the bus.
