1 / 12 page LMC555 CMOS Timer General Description The LMC555 is a CMOS version of the industry standard 555 series general purpose timers. In addition to the stan- dard package (SOIC, MSOP, and MDIP) the LMC555 is also available in a chip sized package (8 Bump micro SMD) using National’s micro SMD package technology. The LMC555 offers the same capability of generating accurate time delays and frequencies as the LM555 but with much lower power dissipation and supply current spikes. When operated as a one-shot, the time delay is precisely controlled by a single external resistor and capacitor. In the stable mode the oscil- lation frequency and duty cycle are accurately set by two external resistors and one capacitor. The use of National Semiconductor’s LMCMOS™ process extends both the fre- quency range and low supply capability. Features n Less than 1 mW typical power dissipation at 5V supply n 3 MHz astable frequency capability n 1.5V supply operating voltage guaranteed n Output fully compatible with TTL and CMOS logic at 5V supply n Tested to −10 mA, +50 mA output current levels n Reduced supply current spikes during output transitions n Extremely low reset, trigger, and threshold currents n Excellent temperature stability n Pin-for-pin compatible with 555 series of timers n Available in 8-pin MSOP Package and 8-Bump micro SMD package Pulse Width Modulator 00866920 00866915 Ordering Information Package Temperature Range Package Marking Transport Media NSC Drawing Industrial −40˚C to +85˚C 8-Pin Small Outline (SO) LMC555CM LMC555CM Rails M08A LMC555CMX 2.5k Units Tape and Reel 8-Pin Mini Small Outline (MSOP) LMC555CMM ZC5 1k Units Tape and Reel MUA08A LMC555CMMX 3.5k Units Tape and Reel 8-Pin Molded Dip (MDIP) LMC555CN LMC555CN Rails N08E 8-Bump micro SMD LMC555CBP F1 250 Units Tape and Reel BPA08EFB LMC555CBPX 3k Units Tape and Reel 8-Bump micro SMD NOPB LMC555CTP F02 250 Units Tape and Reel TPA08EFA LMC555CTPX 3k Units Tape and Reel Note: See Mil-datasheet MNLMC555-X for specifications on the military device LMC555J/883.
