138 / 361 page  Electrical characteristics (rev Y) STM32H753xI 138/360 DS12117 Rev 8 Output voltage levels Unless otherwise specified, the parameters given in Table 60 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 23: General operating conditions. All I/Os are CMOS and TTL compliant. Table 60. Output voltage characteristics for all I/Os except PC13, PC14, PC15 and PI8(1) Symbol Parameter Conditions(3) Min Max Unit VOL Output low level voltage CMOS port(2) IIO=8 mA 2.7 V≤ VDD ≤3.6 V -0.4 V VOH Output high level voltage CMOS port(2) IIO=-8 mA 2.7 V≤ VDD ≤3.6 V VDD−0.4 - VOL(3) Output low level voltage TTL port(2) IIO=8 mA 2.7 V≤ VDD ≤3.6 V -0.4 VOH(3) Output high level voltage TTL port(2) IIO=-8 mA 2.7 V≤ VDD ≤3.6 V 2.4 - VOL(3) Output low level voltage IIO=20 mA 2.7 V≤ VDD ≤3.6 V -1.3 VOH(3) Output high level voltage IIO=-20 mA 2.7 V≤ VDD ≤3.6 V VDD−1.3 - VOL(3) Output low level voltage IIO=4 mA 1.62 V≤ VDD ≤3.6 V -0.4 VOH (3) Output high level voltage IIO=-4 mA 1.62 V≤VDD<3.6 V VDD−-0.4 - VOLFM+(3) Output low level voltage for an FTf I/O pin in FM+ mode IIO= 20 mA 2.3 V≤ VDD≤3.6 V -0.4 IIO= 10 mA 1.62 V≤ VDD ≤3.6 V -0.4 1. The IIO current sourced or sunk by the device must always respect the absolute maximum rating specified in Table 20: Voltage characteristics, and the sum of the currents sourced or sunk by all the I/Os (I/O ports and control pins) must always respect the absolute maximum ratings ΣIIO. 2. TTL and CMOS outputs are compatible with JEDEC standards JESD36 and JESD52. 3. Guaranteed by design. |
