Note: *1: Drive Current Specification
for Push-Pull I/O port only
Sink Current Specification
for both Push-Pull and Open-Drain I/O port.
*2: This Spec. bases on one driver only. There are five build-in drivers actually, so user can
multiply the number of driver to obtain the necessary driver current to drive the speak.
