DESCRIPTION
The HI-1582 low power CMOS transceiver is designed to
meet the requirements of the MIL-STD-1553 and MIL-
STD-1760 specifications. It is a pin-compatible, form and fit
drop-in replacement for the Data Device Corporation MIL-
STD-1553 transceiver, BU-63133L8.
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. A transmitter inhibit control signal is provided.
The receiver section converts the 1553 bus bi-phase data
to complementary CMOS / TTL data suitable for input to a
Manchester decoder. The receiver has a separate enable
input pin, STROBE, which, when low, forces the receiver
outputs to logic "0".
The HI-1582 is packaged in a 32-pin plastic chip-carrier
package (QFN) with an integral exposed heatsink on the
package bottom. The heatsink may be soldered to the PCB
ground plane for optimal thermal dissipation. The HI-1582
is available in industrial (-40°C to +85°C) or extended
(-55°C to +125°C) temperature range options.

FUNCTIONAL DESCRIPTION
RECEIVER
The HI-1582 data bus transceiver contains differential volt-
age 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 inputs TX DATA IN and TX DATA
IN. The transmitter accepts Manchester II bi-phase data
and converts it to differential voltages on TX DATA OUT
and TX DATA OUT. The transceiver outputs are either di-
rect-coupled or transformer-coupled to the MIL-STD-1553
data bus. Both coupling methods produce a nominal volt-
age on the bus of approximately 7.5 volts peak to peak at
the MIL-STD-1553 bus.
The receiver accepts bi-phase differential data from the
MIL-STD-1553 bus through the same direct or transformer
coupled interface at the RX DATA IN and RX DATA IN pins.
The receiver’s differential input stage drives a filter and
threshold comparator to produce CMOS data at the RX
DATA OUT and RX DATA OUT output pins.
The receiver outputs are forced to a logic “0” when the
STROBE pin is low.
MIL-STD-1553 BUS INTERFACE
A direct-coupled interface (see Figure 4) uses a 1:2.5 ratio
isolation transformer and two 55 ohm isolation resistors
between the transformer and the bus. The primary center-
tap of the isolation transformer must be connected to VDD
(3.3V).
The transmitter is automatically inhibited and placed in the
high impedance state when both TX DATA IN and TX DATA
IN are driven with the same logic input state. A logic “1” ap-
plied to the TX INHIBIT or SLEEP input forces the transmit-
ter to the high impedance state, regardless of the state of
TX DATA IN and TX DATA IN.
The SLEEP pin is logically ORed with the TX INHIBIT pin.
In the obsolete BU-63133L8, the SLEEP pin also reduced
idle-state supply current from 30mA to 6mA maximum. The
HI-1582 does not require supply current control; its idle-
state (receive mode) current is 4 mA nominal, lower than
BU-63133L8 sleep current.
In a transformer-coupled interface (see Figure 4), the
transceiver is also connected to a 1:2.5 isolation
transformer. The far end of the stub cable is connected to a
1:1.4 bus coupling transformer, which requires two
coupling resistors equal to 75% of the bus characteristic
impedence (Zo) between the coupling transformer and the
bus.
