Product specification

OM5232

VDD–0.5

0.2VDD+0.9

0.45V

0.2VDD–0.1

NOTE:

AC INPUTS DURING TESTING ARE DRIVEN AT VDD–0.5 FOR A LOGIC ’1’ AND

0.45V FOR A LOGIC ’0’. TIMING MEASUREMENTS ARE MADE AT VIH MIN FOR A

LOGIC ’1’ AND VIL MAX FOR A LOGIC ’0’.

NOTE:

FOR TIMING PURPOSES, A PORT IS NO LONGER FLOATING WHEN A 100MV

CHANGE FROM LOAD VOLTAGE OCCURS, AND BEGINS TO FLOAT WHEN A

100mV CHANGE FROM THE LOADED VOH/VOL LEVEL OCCURS. IOH/IOL > +

20mA.

All other pins are disconnected. VDD = 2V to 5.5V

NOTE:

* Ports 1.6 and 1.7 should be connected to VCC through resistors of sufficiently high value such that the sink current into these pins does not

exceed the IOL1 specification.
