DESCRIPTION
The Si9243AEY is a monolithic bus transceiver designed to
provide bidirectional serial communication in automotive
diagnostic applications.
The device incorporates protection against overvoltages and
short circuits to V
BAT
. The transceiver pin is protected and can be
driven beyond the V
BAT
voltage.
The RX output is capable of driving CMOS or 1
LSTTL load.
The Si9243AEY is built on the Vishay Siliconix BiC/DMOS
process. This process supports bipolar transistors, CMOS, and
DMOS. An epitaxial layer prevents latchup.
The Si9243AEY is available in a 8-pin SO package and
operates over the automotive temperature range (–40 to
125_C).

Notes
a. Room = 25_C, Cold and Hot = as determined by the operating temperature suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. Guaranteed by design, not subject to production test.
e. Minimum pulse width to reset a fault condition.

FUNCTIONAL DESCRIPTION
The Si9243AEY can be either in transmit or receive mode and
it contains over temperature, and short circuit V
BAT
fault
detection circuits.
The voltage on the K and L pins are internally compared to
V
BAT/2
. If the voltage on the K or L pin is less than V
BAT/2
then
RX
K
or RX
L
output will be “low.” If the voltage on the K or L pin
is greater than V
BAT/2
then RX
K
or RX
L
output will be “high.
In order to be in transmit mode, TX must be set “low.” The TX
signal is then internally inverted and turns the MOSFET on,
causing the K pin to be “low.” In transmit mode, the processor
monitors the RX
K
and TX. When the two mirror each other
there is no fault. In the event of over temperature, or short
circuit to V
BAT
, the Si9243AEY will turn off the K output to
protect the IC. The K pin will stay in high impedance and RX
K
will follow the K pin. The fault will be reset when TX is toggled
high. RX
K
, RX
L
and TX pins have internal pull up resistor to
V
DD
while K and L pins have internal pull down resistors. When
any one of the TX, V
BAT
or GND pins is open the K output is off.
When the TX pin is set “high” the Si9243AEY is in receive
mode and the internal MOSFET is turned off. RX
L
and RX
K
outputs will follow L and K inputs respectively.
