Description
Positive supply nominally +5 volts. Connect both pins.
Power and signal ground. Connect all pins.
Notes:
1. CSCHMITT means CMOS Schmitt-trigger inputs.
2. Internal pull-up or pull-down resistors should not be relied upon for proper operation and/or termination of input levels
under all operating conditions without prior consultation with GPS.
