61 / 75 page ![]() DS2148/Q48 61 of 75 11. DC CHARACTERISTICS ABSOLUTE MAXIMUM RATINGS* Voltage Range on Any Pin Relative to Ground -1.0V to +6.0V Operating Temperature Range for DS2148TN -40 °C to +85°C Storage Temperature Range See J-STD-020A specification * This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time can affect reliability. RECOMMENDED DC OPERATING CONDITIONS (-40 °C to +85°C) PARAMETER SYMBOL MIN TYP MAX UNITS NOTES Logic 1 VIH 2.0 5.5 V Logic 0 VIL –0.3 +0.8 V Supply for 5V Operation VDD 4.75 5 5.25 V 1 CAPACITANCE (TA = +25 °C) PARAMETER SYMBOL MIN TYP MAX UNITS NOTES Input Capacitance CIN 5 pF Output Capacitance COUT 7 pF DC CHARACTERISTICS (-40 °C to +85°C; VDD = 5.0V ± 5%) PARAMETER SYMBOL MIN TYP MAX UNITS NOTES Input Leakage IIL –1.0 +1.0 mA 3 Output Leakage ILO 1.0 mA 4 Output Current (2.4V) IOH –1.0 mA Output Current (0.4V) IOL +4.0 mA Supply Current IDD - 95 125 MA 2, 5 NOTES: 1) Applies to VDD. 2) TCLK = MCLK = 2.048MHz. 3) 0.0V < VIN < VDD. 4) Applied to INT* when 3-stated. 5) Power dissipation with TTIP and TRING driving a 30 W load, for an all one’s data density. |
