PIN FUNCTIONS  
DI1 (Pin 1): Driver 1 Input. Do not float.  
DO1A (Pin 2): Driver 1 Noninverting Output.  
DO1B (Pin 3): Driver 1 Inverting Output.  
DI3 (Pin 9): Driver 3 Input. Do not float.  
DO3A (Pin 10): Driver 3 Noninverting Output.  
DO3B (Pin 11): Driver 3 Inverting Output.  
EN (Pin 4, LTC1688): High True Enable Pin, enables all  
four drivers. A low on Pin 4 and a high on Pin 12 will put  
all driver outputs into a high impedance state. See  
Function Tables for details. Do not float.  
ENB (Pin 12, LTC1688):Low True Enable Pin, enables all  
four drivers. A low on Pin 4 and a high on Pin 12 will put  
all driver outputs into a high impedance state. See  
Function Tables for details. Do not float.  
EN12 (Pin 4, LTC1689): Enables Drivers 1 and 2. A low on  
Pin 4 will put the outputs of drivers 1 and 2 into a high  
impedance state. See Function Tables for details. Do not  
float.  
EN34 (Pin 12, LTC1689): Enables Drivers 3 and 4. A low  
on Pin 12 will put the outputs of drivers 3 and 4 into a high  
impedance state. See Function Tables for details. Do not  
float.  
DO2B (Pin 5): Driver 2 Inverting Output.  
DO2A (Pin 6): Driver 2 Noninverting Output.  
DI2 (Pin 7): Driver 2 Input. Do not float.  
DO4B (Pin 13): Driver 4 Inverting Output.  
DO4A (Pin 14): Driver 4 Noninverting Output.  
DI4 (Pin 15): Driver 4 Input. Do not float.  
GND (Pin 8): Ground Connection. A good ground plane is  
recommended for all applications.  
VDD (Pin 16): Power Supply Input. This pin should be  
bypassed with a 0.1µF ceramic capacitor as close to the  
pin as possible. Recommended: VDD = 3V to 5.25V.
