Pinout and package

Pin	Name	Function	Source
1		VL: Input Logic-Supply Voltage. Bypass VL with a 0.1μF ceramic capacitor located as close as possible to the input.
2		RO: Receiver Output. When RE is low and if (A - B) ≥ -50mV, RO is high; if (A - B) ≤ -200mV, RO is low.
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.
4		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.
5		DI: Driver Input. With DE high, a low on DI forces noninverting output low and inverting output high. Similarly, a high on DI forces noninverting output high and inverting output low.
6		GND: Ground
7		N.C.: No Connection. Not internally connected. N.C. can be connected to GND.
8		GND: Ground
9		Y: Noninverting Driver Output
10		Z: Inverting Driver Output
11		B: Inverting Receiver Input
12		A: Noninverting Receiver Input
13		N.C.: No Connection. Not internally connected. N.C. can be connected to GND.
14		VCC: Input Supply Voltage. Bypass VCC with a 1μF ceramic capacitor located as close as possible to the input for full ESD protection.
EP		EP: Exposed Pad (TDFN Only). Connect EP to GND.
