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 transmitter section of these devices is
from the complimentary CMOS /TTL inputs TXA/B and
. This produces a nominal 30V peak to peak signal
acrossa140ohm load.The transmitter isconnectedtothe
bus via a 1:2.5 transformer whose secondary is connected
totwo52ohm isolation resisterswhichfeedthe terminated
70ohmbus.Thiswillproduceanominalvoltageonthebus
of7.5voltspeaktopeak.
TRANSMITTER
TXA/B
The transmitter is automatically inhibited and placed in the
high impedance state when both TXA/B and
theratalogic“1”orlogic“0”simultaneously.Alogic“1:”ap-
plied to the TXINHA/B input will force the transmitter to the
highimpedancestate,regardlessofthestateofTXA/Band
TXA/B
are ei-
The receiver outputs can both be forced to a logic "0"
(HI-1567) or logic “1” (HI-1568) by setting RXENA or
RXENBlow.
TXA/B
RECEIVER
The receiver is transformer coupled to the bus by a 1:1
transformer. Its differential input stage drives a filter and
threshold comparator. CMOS/TTL data is outputted at the
RXA/Band
pins.
