Preliminary data

P89C51RA2/RB2/RC2/RD2xx

VCC–0.5

0.45V

0.2VCC+0.9

0.2VCC–0.1

NOTE:

AC inputs during testing are driven at VCC –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’.

VOH–0.1V

VOL+0.1V

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.
