1 / 31 page LM139-N, LM239-N, LM2901-N, LM3302-N, LM339-N www.ti.com SNOSBJ3D – NOVEMBER 1999 – REVISED MARCH 2013 LM139/LM239/LM339/LM2901/LM3302 Low Power Low Offset Voltage Quad Comparators Check for Samples: LM139-N, LM239-N, LM2901-N, LM3302-N, LM339-N 1 FEATURES APPLICATIONS 2 • Wide Supply Voltage Range • Limit Comparators • LM139/139A Series 2 to 36 VDCor ±1 to ±18 VDC • Simple Analog-to-Digital Converters • LM2901: 2 to 36 VDCor ±1 to ±18 VDC • Pulse, Squarewave and Time Delay Generators • LM3302: 2 to 28 VDCor ±1 to ±14 VDC • Wide Range VCO; MOS Clock Timers • Very Low Supply Current Drain (0.8 mA) — • Multivibrators and High Voltage Digital Logic Independent of Supply Voltage Gates • Low Input Biasing Current: 25 nA DESCRIPTION • Low Input Offset Current: ±5 nA The LM139 series consists of four independent • Offset Voltage: ±3 mV precision voltage comparators with an offset voltage • Input Common-Mode Voltage Range Includes specification as low as 2 mV max for all four GND comparators. These were designed specifically to operate from a single power supply over a wide range • Differential Input Voltage Range Equal to the of voltages. Operation from split power supplies is Power Supply Voltage also possible and the low power supply current drain • Low Output Saturation Voltage: 250 mV at 4 is independent of the magnitude of the power supply mA voltage. These comparators also have a unique characteristic in that the input common-mode voltage • Output Voltage Compatible with TTL, DTL, range includes ground, even though operated from a ECL, MOS and CMOS Logic Systems single power supply voltage. ADVANTAGES The LM139 series was designed to directly interface with TTL and CMOS. When operated from both plus • High Precision Comparators and minus power supplies, they will directly interface • Reduced VOS Drift Over Temperature with MOS logic— where the low power drain of the • Eliminates Need for Dual Supplies LM339 is a distinct advantage over standard comparators. • Allows Sensing Near GND • Compatible with all Forms of Logic • Power Drain Suitable for Battery Operation 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
