NAME
FUNCTION
1
RO
Receiver Output. See the Function Table.
2
RE
Active-Low Receiver-Output 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. RE is a hot-swap input (see the Hot-Swap
Capability section for details).
3
DE
Driver-Output Enable. Drive DE high to enable driver outputs. These outputs are high impedance when
DE is low. Drive RE high and DE low to enter low-power shutdown mode. DE is a hot-swap input (see the
Hot-Swap Capability section for details).
4
DI
Driver Input. With DE high, a low on DI forces the A output low and the B output high. Similarly, a high on
DI forces the A output high and the B output low.
5
GND
Ground
6
A
Noninverting Receiver Input and Noninverting Driver Output
7
B
Inverting Receiver Input and Inverting Driver Output
8
VCC
Positive Supply Voltage Input. Bypass VCC with a 0.1FF ceramic capacitor to GND.
—
EP
Exposed Pad (TDFN Only). Connect EP to GND.
