MCP6566/6R/6U/7/9
DC CHARACTERISTICS (CONTINUED)
Electrical Characteristics: Unless otherwise indicated: V DD = +1.8V to +5.5V, V SS = GND, T A = +25°C, V IN + = V DD /2, V IN - = V SS ,
and R Pull-Up = 20 kΩ to V PU = V DD (see Figure 1-1).
Parameters Symbol Min Typ Max Units Conditions
Push-Pull Output
Pull-up Voltage V PULL_UP 1.6 — 5.5 V
High Level Output Voltage V OH — — V PULL_UP V (see Figure 1-1) (Notes 3, 4)
High Level Output Current leakage I OH_leak — — 1 µA Note 4
Low Level Output Voltage V OL — — 0.6 V I OUT = 3mA/8mA @ V DD = 1.8V/5.5V
Short Circuit Current (Notes 3) I SC — ±30 — mA Not to exceed Absolute Max. Rating
Output Pin Capacitance C OUT — 8 — pF
Note 1: The input offset voltage is the center of the input-referred trip points. The input hysteresis is the difference between the
input-referred trip points.
2: V HYST at different temperatures is estimated using V HYST (T A ) = V HYST @ +25°C + (T A - 25°C) TC 1 + (T A - 25°C) 2 TC 2 .
3: Limit the output current to Absolute Maximum Rating of 50 mA.
4: The pull up voltage for the open drain output V PULL_UP can be as high as the absolute maximum rating of 10.5V. In this
case, I OH_leak can be higher than 1 µA (see Figure 2-30).
