| NJU7141 LOW-VOLTAGE OPERATION TINY SINGLE C-MOS COMPARATOR GENERAL DESCRIPTION The NJU7141 is a low voltage single-power-supply operation single C-MOS comparator with open drain output. The NJU7141 operated from 1 to 5.5V supply and interface with most of TTL and C-MOS type standard logic ICs. The NJU7141 is in MTP-5 package, and it is suitable for battery use items and other portable system. FEATURES Single-Power-Supply Input Offset Voltage Low Operating Current Low Input Bias Current Open Drain Output Output Signal Falling Time C-MOS Technology Package Outline EQUIVALENT CIRCUIT PACKAGE OUTLINE NJU7141F PIN CONFIGURATION ( VDD=1~5.5V ) ( VIO=10mV max.@ 3.0V ) ( IDD=5A typ. ) ( IIB=1pA typ. ) ( 30ns typ. ) MTP5 Ver.2003-03-18 -1- NJU7141 ABSOLUTE MAXIMUM RATINGS ( Ta=25C ) PARAMETER Supply Voltage Differential Input Voltage Common Mode Input Voltage Power Dissipation Operating Temperature Range Storage Temperature Range SYMBOL VIN VID VIC PD Topr Tstg RATINGS 7 7 ( note1 ) -0.3~7 200 -40~+85 -55~+125 UNIT V V V mW C C ( note1 ) If the supply voltage ( VDD ) is less than 7V, the input voltage must not over the VDD level though 7V is limit specified. ( note2 ) Decoupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit.
