FUNCTION
MAX13450E
MAX13451E
1
DE
Driver-Output Enable. Drive DE low to put the driver output in three-state. Drive DE
high to enable the driver. DE is referenced to VL.
2
RE
Receiver-Output Enable. Drive RE low to enable the RO. Drive RE high to disable
the RO output and put the RO output in a high-impedance state. RE is referenced
to VL.
3
DI
Driver Input. Drive DI low to force the noninverting output low and the inverting
output high. Drive DI high to force the noninverting output high and inverting out-
put low. DI is referenced to VL.
4
VCC
Power-Supply Voltage. Bypass VCC to GND with a 0.1FF ceramic capacitor
placed as close as possible to the device.
5
TERM
Active-Low Termination Resistor Enable. Drive TERM low to enable the internal ter-
mination resistor. TERM is referenced to VL.
6
VL
Logic Supply Voltage. Bypass VL to GND with a 0.1FF ceramic capacitor placed
as close as possible to the device.

RO
Receiver Output. When receiver is enabled and VA - VB R -50mV, RO is high. If
VA - VB P -200mV, RO is low. RO is referenced to VL.

RO
Receiver Output. When INV is low, receiver is enabled and VA - VB R -50mV, RO is
high. If VA - VB P -200mV, RO is low. When INV is high, receiver is enabled and
VA - VB R -50mV, RO is low. If VA - VB P -200mV, RO is high. RO is referenced to VL.

A
Noninverting Receiver Input
—
10
A
If INV is low, A is a noninverting receiver input and a noninverting driver output. If
INV is high, A is an inverting receiver input and an inverting driver output.
9
—
B
Inverting Receiver Input
—
12
B
If INV is low, B is an inverting receiver input and an inverting driver output. If INV
is high, B is a noninverting receiver input and a noninverting driver output.
