265 / 308 page ![]() ST7MC1/ST7MC2 265/308 I/O PORT PIN CHARACTERISTICS (Cont’d) 12.8.2 Output Driving Current Subject to general operating conditions for VDD, fOSC, and TA unless otherwise specified. Figure 141. Typical VOL at VDD=5V (standard) Figure 142. Typical VOL at VDD=5V (high-sink) Figure 143. Typical VDD-VOH at VDD=5V Notes: 1. The IIO current sunk must always respect the absolute maximum rating specified in Section 12.2.2 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 Section 12.2.2 and the sum of IIO (I/O ports and control pins) must not exceed IVDD. 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 141) IIO=+5mA 1.2 V IIO=+2mA 0.5 Output low level voltage for a high sink I/O pin when 4 pins are sunk at same time (see Figure 142) IIO=+20mA, TA≤85°C TA≥85°C 1.3 1.5 IIO=+8mA 0.6 VOH 2) Output high level voltage for an I/O pin when 4 pins are sourced at same time (see Figure 143) IIO=-5mA, TA≤85°C TA≥85°C VDD-1.4 VDD-1.6 IIO=-2mA VDD-0.7 0 2 468 10 Iio [mA] 0 0.5 1 1.5 2 2.5 Vol [V] at Vdd=5V Ta=-40°C Ta=25°C Ta=85°C Ta=125°C 0 5 10 15 20 25 30 Iio [mA] 0 0.5 1 1.5 2 Vol [V] at Vdd=5V Ta=-40°C Ta=25°C Ta=85°C Ta=125°C -8 -6 -4 -2 0 Iio [mA] 1 2 3 4 5 6 Vdd-Voh [V] at Vdd=5V Ta=-40°C Ta=25°C Ta=85°C Ta=125°C |
