Type
Description
1
GND
Ground (0V).
2
SELA
I
Channel Enable Select A Input. TTL compatible input used in conjunction with SELB to
power down individual receiver channels. (see table 2).
3
SELB
I
Channel Enable Select B Input. TTL compatible input used in conjunction with SELA to
power down individual receiver channels (see table 2).
4
I/P1
I
Channel 1 Input. TTL compatible.
5
I/P2
I
Channel 2 Input. TTL compatible.
6
I/P3
I
Channel 3 Input. TTL compatible.
7
VCC
Positive Supply (5V).
8
BIAS
I
Bias Current Input. DC level 1.1V nominal. Connect external resistor from pin to ground to
define transmitter output current levels (Rbias 3.9k for Iout=22mA).
9
VEE
Negative Supply (-5V).
10
VREF3
O
Channel 3 Voltage Regulator. Provides 3.3V regulated supply for connection of channel 3
transmit termination network (see
Figure 6). If the driver is disabled, the voltage output at this
pin will be Vcc - 0.7V.
11
O/P3A
O
Channel 3 Differential Output A. Open collector current output. Current sink capability 22mA
nominal (defined by Rbias). When terminated with network to VREF3 provides an output voltage
with inverse phase to I/P3. DC level with TX and RX termination +/-O.275V nominal.
12
O/P3B
O
Channel 3 Differential Output B. Open collector current output. Current sink capability
22mA nominal (defined by Rbias). When terminated with network to VREF3 provides an out-
put voltage in phase with I/P3. DC level with TX and RX termination +/-O.275V nominal.
13
VREF2
O
Channel 2 Voltage Regulator. Provides 3.3V regulated supply for connection of channel 2
transmit termination network (see
Figure 6). If the driver is disabled, the voltage output at this
pin will be Vcc - 0.7V.
14
O/P2A
O
Channel 2 Differential Output A. Open collector current output. Current sink capability 22mA
Nominal (Defined by Rbias). When terminated with network to VREF2 provides an output voltage
with inverse phase to I/P2. DC level with TX and RX termination +/-o.275V nominal.
15
O/P2B
O
Channel 2 Differential Output B. Open collector current output. Current sink capability
22mA nominal (defined by Rbias). When terminated with network to VREF2 provides an out-
put voltage in phase with I/P2. DC level with TX and RX termination +/-O.275V nominal.
