At static “High” or “Low” level TXD, the current source I1 delivers a
current of 3.0 mA (typ). Only during “Low” to “High” transition, does this
current increase to a higher value in order to charge the K Line
capacitor (Cl < 4.0 nF) in a short time.

PIN DESCRIPTION
Pin 1: VCC
Power Supply pin; typically 5.0 V and requiring less than
1.5 mA.
Pin 2: REF–IN–L
Input reference for C2 comparator. This input can be
connected directly to REF–OUT with or without a resistor
network or to an external reference.
Pin 3: REF–IN–K
Input reference for C1 comparator. This input can be
connected directly to REF–OUT with or without a resistor
network or to an external reference.
Pin 4: LO
Output of C2 comparator and normally connected to a
microcontroller I/O. If L input > (REF–IN–L + Hyst/2); output
LO is in high state. If L< (REF–IN–L – Hyst/2); output LO is in
low state and the output transistor is “on”. This pin is an open
collector structure and requires a pull–up resistor to be
connected to VCC. Output drive capability of this output is
5.0 mA.
Pin 5: RXD
Receive output normally connected to a microcontroller
I/O. If DIA input > (REF–IN–L + Hyst/2); output LO is in high
state. If DIA < (REF–IN–L – Hyst/2); output LO is in low state
and the output transistor is “on”. This pin has an internal
pull–up resistor (typically 2.0 kΩ) connected to VCC. Drive
capability of this output is 5.0 mA.
Pin 6: TXD
Transmission input normally connected to a
microcontroller I/O. This pin controls the DIA output. If TXD is
high, the output DIA transistor is in the “off” state. If TXD is
low, the DIA output transistor is “on”.
Pin 9: DIA
Input/Output Diagnosis Bus line pin. This pin is an open
collector structure and is protected against overcurrent and
circuit shorts to Vbat and VS. Whenever the open collector
transistor turns “on” (TXD low), the Bus line is pulled to
ground and the DIA pin current is internally limited to nominal
value of 60 mA. The internal power transistor incorporates a
thermal shutdown circuit which forces the DIA output “off” in
the event of an over temperature condition. The DIA pin is
also the C1 comparator input. It is protected against both
positive and negative overvoltages by an internal 40 V zener
diode. This pin exhibits a constant input current of 7.5 µA.
Pin 10: Gnd
Ground reference for the entire device.
Pin 11: I1
Bus source current pin. It is normally tied to DIA pin and to
the Bus line. The current source I1 delivers a nominal current
of 3.0 mA at static “High” or “Low” levels of TXD. Only during
“Low” to “High” transitions, does this current increase to
a higher value so as to charge the key line capacitor
(Cl < 4.0 nF) in a short time (see Figures 3 and 4).
Pin 12: L
Input for C2 comparator. This pin is protected against both
positive and negative overvoltage by a 40 V zener diode. This
L Line is a second independent input. It can be used for wake
up sequence in ISO diagnosis or as an additional input bus
line. This pin exhibits a constant input current of 7.5 µA.
Pin 13: VS
12 V typical, or Vbat supply pin for the device. This pin is
protected against overvoltage transients.
Pin 14: REF–OUT
Internal reference voltage generator output pin. Its value
depends on VS (Vbat) values. This output can be directly
connected to REF–IN–L and REF–IN–K, or through a
resistor network. Maximum current capability is 50 µA.
