NAME
FUNCTION
1
RO
Receiver Output. When RE is low and (A - B) R -50mV, RO is high; if (A - B) P -200mV, RO is low.
2
RE
Receiver Enable. Drive RE low to enable RO; RO is high impedance when RE is high. Drive RE
high and DE low to enter low-power shutdown mode.
3
DE
Driver Enable. Drive DE high to enable driver output. The driver outputs are high impedance when
DE is low. Drive RE high and DE low to enter low-power shutdown mode.
4
DI
Driver Input. With DE high, a low on DI forces the noninverting output, A, low and the inverting out-
put, B, high. Similarly, a high on DI forces the noninverting output, A, high and the inverting output,
B, low.
5
GND
Ground

A
Noninverting Receiver Input and Noninverting Driver Output

B
Inverting Receiver Input and Inverting Driver Output
8
VCC
Positive Supply. Bypass VCC to GND with a 0.1FF ceramic capacitor as close as possible to the
device.

EP
Exposed Pad (TDFN Only). Connect EP to GND.
