NJU7108 LOW POWER AND LOW OFFSET VOLTAGE SUPER SMALL-SIZED SINGLE C-MOS COMPARATOR ■GENERAL DESCRIPTION The NJU7108 is a super small-sized package single C-MOS comparator with push pull output. The operating voltage is from 1V to 5.5V, and the interface can be connected with most of TTL and C-MOS type standard logic ICs. Furthermore, The input offset voltage is lower than 4mV and the package is super small-sized SC88A, therefore they can be suitable for battery use items and other portable items. ■PACKAGE INFORMATION ■FEATURES ●Single Low Power Supply ●Low Offset Voltage ●Low Operating Current ●Push Pull Output ●Package Outline ●C-MOS Technology ■PIN CONFIGURATION (Top View) VDD=1.0~5.5V VIO=4mV max IDD=10uA typ SC88A NJU7108F3 IN- 1 5 VDD VSS 2 IN+ 3 4 OUT ■EQUIVALENT CIRCUIT VDD INOUT IN+ VSS 2003/07/16 ( 1 / 3 ) NJU7108 ■ABSOLUTE MAXIMUM RATINGS (Ta=25°C) PARAMETER SYMBOL RATING UNIT Supply Voltage VDD 7.0 V Differential Input Voltage VID V ±7.0 (Note1) Common Mode Input Voltage VIC -0.3~7.0 V Power Dissipation PD 250 (Note2) mW Operating Temperature Topr -40~+85 °C Storage Temperature Tstg -55~+125 °C Note1) If the supply voltage (VDD) is less than 7.0V, the input voltage must not over the VDD level though 7.0V is limit specified. Note2) The power dissipation is value mounted on aglass epoxy board (FR-4) in size of 50x50x1.6 millimeters square. Note3) Decoupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit. ■ELECTRICAL CHARACTERISTICS PARAMETER Operating Voltage Input Offset Voltage Input Offset Current Input Bias Current Input Common Mode Voltage Range High Level Output Voltage Low Level Output Voltage Operating Current SYMBOL VDD VIO IIO IIB PARAMETER Propagation Delay Low to High Propagation Delay High to Low Output Signal Rising Time Output Signal Falling Time SYMBOL CONDITIONS VIN=VDD/2 VICM VOH VOL IDD IOH=-5mA IOL=+5mA CONDITIONS MIN 1.0 - (VDD=3.0V,RL=∞,Ta=25°C) TYP MAX UNIT 5.5 V 4 mV 1 pA 1 pA 0~2.5 - - V 2.7 - 10 0.3 20 V V uA (VDD=3.0V,f=10kHz,CL=15pF,Ta=25°C) MIN TYP MAX UNIT tPLH Over Drive=100mV - 500 - ns tPHL Over Drive=100mV - 190 - ns tTLH tTHL Over Drive=100mV Over Drive=100mV - 10 5 - ns ns 2003/07/16 ( 2 / 3 ) NJU7108 ■SWITCHING CHARACTERISTICS MEASUREMENT CIRCUIT VDD PULSE GENERATER 50ohm 1uF VDD DUT 10 Turn 0V 0.1uF CL ■TYPICAL CHARACTERISTICS Output Voltage vs. Output Current (Source) Output Voltage VOH (V) OutputVoltage VOL (V) Output Voltage vs. Output Current (Sink) 3.0 2.5 2.0 1.5 1.0 0.5 0.0 0 5 10 15 20 25 Output Current IOL (mA) 30 3.0 2.5 2.0 1.5 1.0 0.5 0.0 0 5 10 15 20 25 30 Output Current IOH (mA) [CAUTION] The specifications on this data book are only given for information , without any guarantee as regards either mistakes or omissions.
