| NJU7112A/14A C-MOS COMPARATOR WITH OPEN DRAIN OUTPUT GENERAL DESCRIPTION The NJU7112A and 14A dual and quad C-MOS Comparators performing wide operating voltage from 3 to 16V,low operating current and low offset voltage. The NJU7112A and 14A operated on a single-power-supply can interface with most of TTL and C-MOS type standard logic ICs. FEATURES Single-Power-Supply Wide Operating Voltage Low Operating Current Wide Common Mode Input Voltage High Input Impedance Low Bias Current Low Offset Voltage Open Drain Output Package Outline C-MOS Technology PIN CONFIGURATION PACKAGE OUTLINE NJU7112AD NJU7112AM ( VDD=3~16V ) ( 11A/circuit typ. ) ( 0~3.8V @ VDD=5V ) ( IIB=1pA ) NJU7114AD NJU7114AM DIP/DMP8 ( NJU7112A ) DIP/DMP14 ( NJU7114A ) NJU7112AD/AM NJU7114AD/AM EQUIVALENT CIRCUIT Ver.2003-03-18 -1- NJU7112A/14A ABSOLUTE MAXIMUM RATINGS ( Ta=25C ) PARAMETER Supply Voltage Differential Input Voltage Input Voltage Output Voltage Output Current Power Dissipation Operating Temperature Range Storage Temperature Range SYMBOL VDD VID VI VO IO PD Topr Tstg RATINGS 18 18 ( note1 ) 18 18 20 ( DIP8 ) 500 ( DIP14 ) 700 ( DMP8 ) 300 ( DMP14 ) 300 0~+70 -40~+125 UNIT V V V V mA mW C C ( note1 ) If the supply voltage ( VDD ) is less than 18V, the input voltage must not over the VDD level though 18V is limit specified.
