NOTES:
1. INTRN or OP3 – OP7 when used as interrupt outputs.
2. The test for open-drain outputs is intended to guarantee switching of the output transistor. Measurement of this response is referenced from themidpoint of the switching signal, VM, to a
point 0.5V above VOL. This point represents noise margin that assures true switching has occurred. Beyond this level, the effects of external circuitry and test environment are pronounced
and can greatly affect the resultant measurement.

OPEN
When using an external clock it is preferred to drive X2 and leave X1 open.
X2 is the input to the internal driver, while X1 is the output.

CIRCUITS
R1
U1
R1 is only required if U1 will not drive to X2 high level.
Previous specifications indicated X2 should be grounded and X1
should be driven. This is still acceptable. It is electrically easier to drive
the amplifier input than to overdrive its output.
