TERM100
Termination Resistor Value Selection Input. Drive TERM100 low to select a 120I
termination and high to select a 100I termination. The TERM100 input is refer-
enced to VL.
14
SRL
Slew-Rate Limiting-Enable Input. Drive SRL high to enable slew-rate limiting and
low to disable slew-rate limiting. The SRL input is referenced to VL.
—
8
INV
Inversion Input. Drive INV high to internally swap RO logic level with respect to A
and B signals.
—
9
FAULT
Fault Flag Output. FAULT asserts high in overcurrent conditions or if A/B are forced
below GND or above VCC when the driver is enabled. FAULT is referenced to VL.
—
EP
Exposed Pad. Connect EP to GND. Do not use EP as the only GND connection.
