Pin Function
Enable pin for output A. TTL/CMOS-compatible logic input. A logic-level high enables the
device. An internal pull-up enables the part if pin is open. A logic-level low disables the device
and the output will be low regardless of the input state.
Control Input A: TTL/CMOS-compatible logic input. Connect to V
DD
or ground if not used and
connect ENA to ground to disable driver A.
Ground
Control Input B: TTL/CMOS compatible logic input. Connect to V
DD
or ground if not used and
connect ENB to ground to disable driver B.
Output B: Parallel Bipolar/CMOS output.
Voltage Supply Input: +4.5V to +18V
Output A: Parallel Bipolar/CMOS output.
Enable pin for output B. TTL/CMOS-compatible logic input. A logic-level high enables the
device. An internal pull-up enables the part if pin is open. A logic-level low disables the device
and the output will be low regardless of the input state.
Exposed thermal pad for ePad MSOP package only (Not available on SOIC-8L package).
Connect to ground. Must make a full connection to the ground plane to maximize thermal
performance of the package.
