100 / 149 page  Electrical characteristics STM32F411xC STM32F411xE 100/149 DocID026289 Rev 6 Output voltage levels Unless otherwise specified, the parameters given in Table 54 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 14. All I/Os are CMOS and TTL compliant. Table 54. Output voltage characteristics Symbol Parameter Conditions Min Max Unit VOL(1) 1. The IIO current sunk by the device must always respect the absolute maximum rating specified in Table 12. and the sum of IIO (I/O ports and control pins) must not exceed IVSS. Output low level voltage for an I/O pin CMOS port(2) IIO = +8 mA 2.7 V ≤VDD ≤3.6 V 2. TTL and CMOS outputs are compatible with JEDEC standards JESD36 and JESD52. -0.4 V VOH(3) 3. The IIO current sourced by the device must always respect the absolute maximum rating specified in Table 12 and the sum of IIO (I/O ports and control pins) must not exceed IVDD. Output high level voltage for an I/O pin VDD–0.4 - VOL (1) Output low level voltage for an I/O pin TTL port(2) IIO =+8 mA 2.7 V ≤VDD ≤3.6 V -0.4 V VOH (3) Output high level voltage for an I/O pin 2.4 - VOL(1) Output low level voltage for an I/O pin IIO = +20 mA 2.7 V ≤VDD ≤3.6 V -1.3(4) 4. Guaranteed by characterization results. V VOH(3) Output high level voltage for an I/O pin VDD–1.3(4) - VOL(1) Output low level voltage for an I/O pin IIO = +6 mA 1.8 V ≤VDD ≤3.6 V -0.4(4) V VOH(3) Output high level voltage for an I/O pin VDD–0.4(4) - VOL(1) Output low level voltage for an I/O pin IIO = +4 mA 1.7 V ≤VDD ≤3.6 V -0.4(5) 5. Guaranteed by design. V VOH(3) Output high level voltage for an I/O pin VDD–0.4(5) - |
