LMC555CN Timer

Product Overview

Part Number: LMC555CN 

Manufacturer: Texas Instruments

Description: 8-PDIP 555 Type Timer/Oscillator IC, 3MHz (2-PDIP).

Lead Time: Can Ship Immediately

Datasheet: Datasheet PDF

Category: Integrated Circuits (ICs), Power Management (PMIC), Voltage Regulators - DC DC Switching Regulators

Number of Pins: 8

Short Description

It is equipped with an 8-DIP timer clock (0.300, 7.62mm) integrated into the packaging. On the programmable timer, the frequency is set to 3MHz. Tube cases are packed with it. A hole should be drilled into the wall for mounting the programmable timer. A 555 type chip is a single oscillator and timer. It operates between -40°C and 85°C. Through-hole mounting is required for this digital timer. 

 

For operating supply voltage, a 50-A voltage is rated. A LMC555 is used in it. There are eight pins on the timer clock. The programmable timer has a supply voltage of 5V. A chip with 8 pins has 8 pins in total. A total of eight terminations are present on the chip. There is 930.006106mg of weight in the timer clock. There is 50 amps of quiescent current running through the timer clock.

 

General purpose timers of the 555 series are also available in CMOS. As well as the chip-size package (8 Bump micro SMD), the LMC555 is also available in standard packages (SOIC, MSOP, and MDIP). In addition to producing time delays and frequencies, the LMC555 doesn't dissipate as much power and has less spikes in current. A single external resistor and capacitor controls the time delay when operated as a one-shot. During the stable mode, two external resistors and one capacitor are used to accurately set the frequency and duty cycle of the oscillation. In addition to extending the frequency range, LMCMOSTM from National Semiconductor also offers low supply capabilities.
