| UNISONIC TECHNOLOGIES CO., LTD LM393 DUAL DIFFERENTIAL COMPARATOR SOP-8 LINEAR INTEGRATED CIRCUIT DESCRIPTION The UTC LM393 consists of two independent voltage comparators, designed specifically to operate from a single power supply over a wide voltage range. TSSOP-8 FEATURES * Single or dual supply operation. * Wide operating supply range (VCC=2V ~ 36V or 1 ~ 18V) * Input common-mode voltage includes ground. * Low supply current drain ICC=0.8mA (Typical). * Low input bias current IBIAS=25nA (Typical). * Output compatible with TTL, DTL, and CMOS logic system. DIP-8 *Pb-free plating product number: LM393L ORDERING INFORMATION Ordering Number Normal Lead Free Plating LM393-D08-T LM393L-D08-T LM393-P08-R LM393L-P08-R LM393-P08-T LM393L-P08-T LM393-S08-R LM393L-S08-R LM393-S08-T LM393L-S08-T Package DIP-8 TSSOP-8 TSSOP-8 SOP-8 SOP-8 Packing Tube Tape Reel Tube Tape Reel Tube www.unisonic.com.tw Copyright (c) 2005 Unisonic Technologies Co., Ltd 1 of 6 QW-R104-002,F LM393 PIN DESCRIPTION LINEAR INTEGRATED CIRCUIT OUT 1 1 8 Vcc IN 1(-) 2 7 OUT 2 IN 1(+) 3 6 IN 2(-) GND 4 5 IN 2(+) BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R104-002,F LM393 ABSOLUTE MAXIMUM RATINGS LINEAR INTEGRATED CIRCUIT PARAMETER SYMBOL RATINGS UNIT 18 or 36 Supply Voltage VCC V Differential Input Voltage VI(DIFF) 36 V Input Voltage VIN -0.3 ~ +36 V Power Dissipation PD 570 mW Operating Temperature Range TOPR 0 ~ +70 C Storage Temperature Range TSTG -65 ~ +150 C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
