DS21714E-page 3 MCP6546/6R/6U/7/8/9 AC CHARACTERISTICS Open-Drain Output Output Pull-Up Voltage VPU 1.6 — 10 V (Note 4) High-Level Output Current IOH -100 — — nA VDD = 1.6V to 5.5V, VPU = 10V (Note 4) Low-Level Output Voltage VOL VSS —VSS + 0.2 V IOUT = 2 mA, VPU = VDD = 5V Short-Circuit Current ISC —±1.5 — mA VPU = VDD = 1.6V (Note 4) ISC –30 — mA VPU = VDD = 5.5V (Note 4) Output Pin Capacitance COUT —8 — pF Electrical Specifications: Unless otherwise indicated, VDD = +1.6V to +5.5V, VSS = GND, TA = 25°C, VIN+ = VDD/2, Step = 200 mV, Overdrive = 100 mV, RPU =2.74 kΩ to VPU = VDD, and CL = 36 pF (Refer to Figure 1-2 and Figure 1-3). Parameters Sym Min Typ Max Units Conditions Fall Time tF —0.7 — µs (Note 1) Propagation Delay (High-to-Low) tPHL —4.0 8.0 µs Propagation Delay (Low-to-High) tPLH —3.0 8.0 µs (Note 1) Propagation Delay Skew tPDS —-1.0 — µs (Notes 1 and 2) Maximum Toggle Frequency fMAX — 225 — kHz VDD = 1.6V fMAX — 165 — kHz VDD = 5.5V Input Noise Voltage Eni — 200 — µVP-P 10 Hz to 100 kHz Note 1: tR and tPLH depend on the load (RL and CL); these specifications are valid for the indicated load only. 2: Propagation Delay Skew is defined as: tPDS = tPLH - tPHL. DC CHARACTERISTICS (CONTINUED) Electrical Specifications: Unless otherwise indicated, VDD = +1.6V to +5.5V, VSS = GND, TA = 25°C, VIN+ = VDD/2, VIN– = VSS, RPU =2.74kΩ to VPU = VDD (Refer to Figure 1-3). Parameters Sym Min Typ Max Units Conditions 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: VHYST at differential temperatures is estimated using: VHYST (TA) = VHYST + (TA -25°C) TC1 + (TA - 25°C)2TC2. 3: Input bias current at temperature is not tested for the SC-70-5 package 4: Do not short the output above VSS + 10V. Limit the output current to Absolute Maximum Rating of 30 mA. The minimum VPU test limit was VDD before Dec. 2004 (week code 52). MCP6548 CHIP SELECT (CS) CHARACTERISTICS Electrical Specifications: Unless otherwise indicated, VDD = +1.6V to +5.5V, VSS = GND, TA = 25°C, VIN+ = VDD/2, VIN– = VSS, RPU =2.74kΩ to VPU = VDD, and CL = 36 pF (Refer to Figures 1-1 and 1-3).
