HI-8590
FUNCTIONAL DESCRIPTION
Figure 1 is a block diagram of the line driver. The +5V and
-5V levels are generated internally using on-chip zeners.
Currents for slope control are set by zener voltages across
on-chipresistors.
The TX0IN and TX1IN inputs receive logic signals from a
control transmitter chip such as the HI-6010 or HI-8282.
TXAOUT and TXBOUT hold each side of the ARINC bus at
Ground until one of the inputs becomes a One. If for exam-
pleTX1INgoeshigh,achargingpathisenabledto5Vonan
“A” side internal capacitor while the “B” side is enabled to
-5V. The charging current is selected by the SLP1.5 pin. If
SLP1.5 is high, the capacitor is nominally charged from
10%to90%in1.5μs. Iflow,theriseandfalltimesare10μs.
A unity gain buffer receives the internally generated slopes
and differentially drives the ARINC line. Current is limited
by the series output resistors at each pin. There are no
fuses in series with the ARINC outputs of the HI-8590 as
existsontheHI-8382.
The HI-8590 has 37.5 ohms in series with each ARINC out-
put just like the HI-8585. The HI-8586 has 10 ohms in se-
ries. The HI-8586 is used with the HI-8588 for applications
where more series resistance is added externally, typically
forlightningprotectiondevices.
