TYPICAL PERFORMANCE CHARACTERISTICS
LTC1520
PIN
4
B1 (Pin 1): Receiver 1 Inverting Input.
A1 (Pin 2): Receiver 1 Noninverting Input.
RO1 (Pin 3): Receiver 1 Output.
Enable (Pin 4): Receiver Output Enable Pin. A logic high
input enables the receiver outputs. A logic low input
forces the receiver outputs into a high impedance state.
Do not float.
RO2 (Pin 5): Receiver 2 Output.
A2 (Pin 6): Receiver 2 Noninverting Input.
B2 (Pin 7): Receiver 2 Inverting Input.
GND (Pin 8): Ground Pin. A ground plane is recommended
for all LTC1520 applications.
