The HI-1567 family of data bus transceivers contain differ-
ential voltage source drivers and differential receivers.
They are intended for applications using a MIL-STD-1553
A/B data bus. The device produces a trapezoidal output
waveformduringtransmission.
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
convertsittodifferentialvoltageson
The transceiver outputs are either direct or transformer
coupled to the MIL-STD-1553 data bus.

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
outputpins.

Each set of receiver outputs can be independently forced
to a logic "0" (HI-1567) or logic “1” (HI-1568) by setting
RXENAorRXENBlow.
Adirect coupled interface (see Figure 2) uses a 1:2.5 ratio
isolation transformer and two 55 ohm isolation resistors
betweenthetransformerandthebus.
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.
