29 / 36 page ![]() ST7LNB1Y0 Electrical characteristics 29/36 Figure 13. Typical IPU vs. VDD with VIN=VSS 5.6.2 Output driving current Subject to general operating conditions for VDD, fCPU, and TA unless otherwise specified. 0 10 20 30 40 50 60 70 80 90 22 .5 33 .5 4 4.5 55 .5 6 Vdd (V) T a = 1 40°C Ta = 9 5 °C Ta = 2 5 °C Ta = -4 5 ° C Table 30. Output driving current characteristics Symbol Parameter Conditions Min Max Unit VOL (1) Output low level voltage for a standard I/O pin when 8 pins are sunk at same time (see Figure 14) IIO=+5 mA 1.0 V IIO=+2 mA 0.4 Output low level voltage for a high sink I/O pin when 4 pins are sunk at same time (see Figure 15) IIO=+20 mA 1.3 IIO=+8 mA 0.75 VOH (2) Output high level voltage for an I/O pin when 4 pins are sourced at same time (see Figure 16) IIO=-5 mA VDD−1.5 IIO=-2 mA VDD−0.8 1. The IIO current sunk must always respect the absolute maximum rating specified in Table 19 and the sum of IIO (I/O ports and control pins) must not exceed IVSS. 2. The IIO current sourced must always respect the absolute maximum rating specified in Table 19 and the sum of IIO (I/O ports and control pins) must not exceed IVDD. True open drain I/O pins does not have VOH. |
