Notes:
1. The
RESET
pin has an internal pull-up resistor with a resistance of about 30 K
.
2. Pins HIN and VIN have an internal pull-down resistor with a resistance of about 200 K
.
3. Pins P1, P2, and P3 (except P1.0-P1.3 and P1.5) source a transition current when they are being externally
driven from 1 to 0. The transition current reaches its maximum value when V
IN
is approximately 2V.
4.
RESET
is a Schmitt trigger input, and OSCIN is a CMOS input.
5. HIN and V
IN
are Schmitt trigger inputs.
