| INTEGRATED CIRCUITS DATA SHEET RAA28 Infrared I2C remote control decoder Product specification 2002 Apr 13 D.C. Characteristics TA = -40C to 85C, VCC = 2.7 V to 6.0 V (unless otherwise noted) Symbol Parameter VIL VIH VIH1 VOL Input Low Voltage Input High Voltage Input High Voltage Output Low Voltage (Ports 1, 3) (1) Condition (Except XTAL1, RST) (XTAL1, RST) IOL = 20 mA, VCC = 5 V IOL = 10 mA, VCC = 2.7 V IOH = -80 A, VCC = 5 V 10% IOH = -30 A IOH = -12 A VIN = 0.45 V VIN = 2 V 0 < VIN < VCC VCC = 5 V Min -0.5 0.2 VCC+0.9 0.7 VCC Max 0.2 VCC-0.1 VCC+0.5 VCC+0.5 0.5 Units V V V V V V V VOH Output High Voltage (Ports 1, 3) Logical 0 Input Current (Ports 1, 2, 3) Logical 1 to 0 Transition Current (Ports 1, 2, 3) Input Leakage Current (Port P1.0, P1.1) Comparator Input Offset Voltage Comparator Input Common Mode Voltage Reset Pulldown Resistor Pin Capacitance Power Supply Current 2.4 0.75 VCC 0.9 VCC -50 -750 10 20 0 50 VCC 300 10 15/5.5 5/1 100 20 IIL ITL ILI VOS VCM RRST CIO A A A mV V K pF mA mA A A Test Freq. = 1 MHz, TA = 25C Active Mode, 12 MHz, VCC = 6 V/3 V Idle Mode, 12 MHz, VCC = 6 V/3 V P1.0 & P1.1 = 0V or VCC VCC = 6 V P1.0 & P1.1 = 0V or VCC VCC = 3 V P1.0 & P1.1 = 0V or VCC ICC Power Down Mode(2) Notes: 1. Under steady state (non-transient) conditions, IOL must be externally limited as follows: Maximum IOL per port pin:20 mA Maximum total IOL for all output pins:80 mA If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test conditions. 2. Minimum VCC for Power Down is 2 V.
