The transmitter is automatically inhibited and placed in the
high impedance state when both TXA/B and
ther at a logic “1” or logic “0” simultaneously. Alogic “1” ap-
plied to the TXINHA/B input will force the transmitter to the
high impedance state, regardless of the state of TXA/B and

The HI-1570 data bus transceiver contains differential volt-
age source drivers and differential receivers. They are in-
tended for applications using a MIL-STD-1553 A/B data
bus. The device produces a trapezoidal output waveform
during transmission.
Data input to the device’s transmitter section is from the
complementary CMOS / TTL inputs TXA/B and
The transmitter accepts Manchester II bi-phase data and
converts it to differential voltages on
The transceiver outputs are either direct or transformer cou-
pled to the MIL-STD-1553 data bus. Both coupling meth-
ods produce a nominal voltage on the bus of 7.5 volts peak
to peak at V
A&B = 5.0 Vdc. Refer to Figure 4 for
transmitter output amplitudes at other values of
A&B between 0 - 5 Vdc. (Contact your Holt Sales Repre-
sentative about the 0 - 10 Vdc Control Voltage option).

RECEIVER
The receiver accepts bi-phase differential data from the
MIL-STD-1553 bus through the same direct or transformer
coupled interface as the transmitter. The receiver’s differ-
ential input stage drives a filter and threshold comparator
that produces CMOS/TTL data at the RXA/B and
output pins.
/
RXA B
Each set of receiver outputs can be independently forced
to a logic "0" by setting RXENAor RXENB low.
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
impedance (Zo) between the coupling transformer and the
bus.
