In addition to the standard package (SOIC, VSSSOP, and PDIP) the LMC555 is also available in a chipsized package (8-bump DSBGA) using TI's DSBGA 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 theastable mode the oscillation frequency and duty cycle are accurately set by two external resistors and one capacitor. The use of TI's LMCMOS process extends both the frequency range and the low supply capability.  \nDevice Information(1)  \n\n| PART NUMBER | PACKAGE | BODY SIZE (NOM) |\n| --- | --- | --- |\n| LMC555 | SOIC (8) | 4.90 mm × 3.91 mm |\n|  | VSSOP (8) | 3.00 mm × 3.00 mm |\n|  | PDIP (8) | 9.81 mm × 6.35 mm |\n|  | DSBGA (8) | 1.43 mm × 1.41 mm |\n\n(1) For all available packages, see the orderable addendum atthe end of the data sheet.  \nPulse Width Modulator Pulse Width Modulator Waveform:  \nTop Waveform-Modulation Bottom Waveform-Output Voltage  \nAn IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
