55 / 73 page ![]() STR750F Electrical parameters 55/71 Table 32. Output driving current I/O Output Drive characteristics for VDD_IO = 3.0 to 3.6 V and EN33 bit =1 or VDD_IO = 4.5 to 5.5 V and EN33 bit =0 I/O Type Symbol Parameter Conditions Min Max Unit O2 VOL (1) 1. The IIO current sunk must always respect the absolute maximum rating specified in Section 3.2.2 and the sum of IIO (I/O ports and control pins) must not exceed IVSS_IO. Output low level voltage for a standard I/O pin when 8 pins are sunk at same time IIO=+2 mA 0.4 V VOH (2) 2. The IIO current sourced must always respect the absolute maximum rating specified in Section 3.2.2 and the sum of IIO (I/O ports and control pins) must not exceed IVDD_IO. Output high level voltage for an I/O pin when 4 pins are sourced at same time IIO=-2 mA VDD_IO-0.8 O4 VOL (1) Output low level voltage for a standard I/O pin when 8 pins are sunk at same time IIO=+4 mA 0.4 VOH (2) Output high level voltage for an I/O pin when 4 pins are sourced at same time IIO=-4 mA VDD_IO-0.8 O8 VOL (1) Output low level voltage for a standard I/O pin when 8 pins are sunk at same time IIO=+8 mA 0.4 Output low level voltage for a high sink I/O pin when 4 pins are sunk at same time IIO=+20 mA, TA≤85°C TA≥85°C 1.3 1.5 IIO=+8 mA 0.4 VOH (2) Output high level voltage for an I/O pin when 4 pins are sourced at same time IIO=-8 mA VDD_IO-0.8 |
