UNISONIC TECHNOLOGIES CO., LTD LM339
QUAD DIFFERENTIAL COMPARATOR
SOP-14
LINEAR INTEGRATED CIRCUIT
DESCRIPTION
The UTC LM339 consists of four independent voltage comparators, designed specifically to operate from a single power supply over a wide voltage range.
TSSOP-14
FEATURES
*Signal or dual supply operation. *Wide operating supply range (Vcc=2V~36V). *Input common-mode voltage includes ground. *Low supply current drain IF=0.8mA (Typical). *Open collector outputs for wired and connection. *Low input bias current IBIAS=25nA (Typical). *Low output saturation voltage. *Output compatible with TTL, DTL, and CMOS logic system.
DIP-14
*Pb-free plating product number: LM339L

PARAMETER SYMBOL RATINGS UNIT Supply Voltage Vcc +- 18 or 36 V Differential input Voltage VI(DIFF) 36 V Input Voltage VIN -0.3~36 V Power Dissipation PD 570 mW Junction Temperature TJ 125 C Operating Temperature TOPR 0 ~ +70 C Storage Temperature TSTG -40 ~ 150 C Note 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. The device is guaranteed to meet performance specification within 0 ~ 70 operating temperature range and assured by design from -20 ~ +85 .
