Package: 8 SO
PinNameFunctionSource
1RO: Receiver Output. If A > B by 200mV, RO will be high; if A < B by 200mV, RO will be low.
2DI: Driver Input. A low on DI forces output Y low and output Z high. Similarly, a high on DI forces output Y high and output Z low.
3GND: Ground
4Y: Noninverting Driver Output
5Z: Inverting Driver Output
6A: Noninverting Receiver Input and Noninverting Driver Output
7B: Inverting Receiver Input and Inverting Driver Output
8VCC: Positive Supply: 3.0V ≤ VCC ≤ 3.6V. Do not operate device with VCC > 3.6V
