LMC7221 Datasheet | National Semiconductor

Description The LM7221 is a micropower CMOS parator available in the space saving SOT23-5 package. This makes this parator ideal for space and weight critical designs. The LMC7221 is also available in the SO-8 package. The LMC7221 is supplied in two offset voltage grades, 5 m V and 15 m V. The open drain output can be pulled up with a resistor to a voltage which can be higher or lower than the supply voltage - this makes the part useful for mixed voltage systems. For a tiny parator with a push-pull output, please see the LMC7211 datasheet. n n n n n n Guaranteed specs at 2.7V, 5V, 15V supplies Typical supply current 7 µA at 5V Response time of 4 µs at 5V LMC7221 - open drain output Input mon-mode range beyond V- and V+ Low input current Applications n n n n n n n Mixed voltage battery powered products Notebooks and PDAs PCMCIA cards Mobile munications Alarm and security circuits Driving low current LEDs Direct sensor interface Features n Tiny SOT 23-5 package saves space n Package is less than 1.43 mm thick Connection Diagrams 8- Pin SO-8 5-Pin SOT23-5 DS012346-1 DS012346-2 Top View Top View Ordering Information Package Ordering Information LMC7221AIM 8-Pin SO-8 LMC7221AIMX LMC7221BIM LMC7221BIMX LMC7221AIM5 5-Pin SOT 23-5 LMC7221AIM5X LMC7221BIM5 LMC7221BIM5X NSC Drawing Number M08A M08A M08A M08A MA05A MA05A MA05A MA05A Package Marking LMC7221AIM LMC7221AIM LMC7221BIM LMC7221BIM C01A C01A C01B C01B Rails 2.5k Units Tape and Reel Rails 2.5k Units Tape and Reel 1k Units Tape and Reel 3k Units Tape and Reel 1k Units Tape and Reel 3k Units Tape and Reel Transport Media © 1999 National Semiconductor Corporation DS012346 .national.
