1 / 20 page LMC7221 www.ti.com SNOS748E – SEPTEMBER 1999 – REVISED MARCH 2013 LMC7221 Tiny CMOS Comparator with Rail-To-Rail Input and Open Drain Output Check for Samples: LMC7221 1 FEATURES DESCRIPTION The LM7221 is a micropower CMOS comparator 2 • Tiny 5-Pin SOT-23 package saves space available in the space saving 5-Pin SOT-23 package. • Package is less than 1.43 mm thick This makes this comparator ideal for space and • Ensured specs at 2.7V, 5V, 15V supplies weight critical designs. The LMC7221 is also available in the 8-Pin SOIC package. The LMC7221 • Typical supply current 7 μA at 5V is supplied in two offset voltage grades, 5 mV and 15 • Response time of 4 μs at 5V mV. • LMC7221—open drain output The open drain output can be pulled up with a • Input common-mode range beyond V− and V+ resistor to a voltage which can be higher or lower • Low input current than the supply voltage—this makes the part useful for mixed voltage systems. APPLICATIONS For a tiny comparator with a push-pull output, please • Mixed voltage battery powered products see the LMC7211 datasheet. • Notebooks and PDAs • PCMCIA cards • Mobile communications • Alarm and security circuits • Driving low current LEDs • Direct sensor interface Connection Diagram 8-Pin SOIC - Top View 5-Pin SOT-23 - Top View Figure 1. See Package Number D0008A Figure 2. See Package Number DBV0005A These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 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.
