If A > B by 200mV, RO will be high; if A < B by 200mV, RO will be low. 3 Receiver Output Enable. RO is enabled when RE is low; RO is high imped- ance when RE is high. If RE is high and DE is low, the device will enter a low-power shutdown mode. 4 Driver Output Enable. The driver outputs are enabled by bringing DE high. They are high impedance when DE is low. If RE is high and DE is low, the device will enter a low-power shutdown mode. If the driver outputs are enabled, the parts function as line drivers. While they are high impedance, they function as line receivers if RE is low. 5 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. 6, 7 Ground 9 Noninverting Driver Output 10 Inverting Driver Output — Noninverting Receiver Input and Noninverting Driver Output 12 Noninverting Receiver Input RO – RE DE DI GND Y Z A A — B Inverting Receiver Input and Inverting Driver Output 11 B Inverting Receiver Input 13, 14 VCC Positive Supply: 3.0V ≤ VCC ≤ 3.6V 1, 8 N.C.
