LMC555CBP

Programmable Timers And Oscillators Overview

The LMC555CBP is a CMOS version of the industry standard 555 series general-purpose timer manufactured by Texas Instruments. It offers accurate time delay and frequency generation capabilities with significantly lower power dissipation and supply current spikes compared to bipolar counterparts. The device operates on a single power supply ranging from 1.5 V to 15 V. It supports both monostable (one-shot) and astable modes, where timing parameters are controlled by external resistors and capacitors. The component features excellent temperature stability and low reset, trigger, and threshold currents.

Programmable Timers And Oscillators Feature Summary

• Sequential timing events

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'BP' against official Texas Instruments documentation to confirm package type and availability status. Ensure sourcing from authorized distributors to guarantee authenticity, as markings may vary between National Semiconductor and Texas Instruments branding. Confirm RoHS compliance and operating temperature range requirements match your design specifications before procurement.

Programmable Timers And Oscillators Selection Notes

Select this component when low power consumption is critical compared to bipolar 555 timers. It is suitable for battery-operated devices due to its wide voltage range starting at 1.5 V. Consider the PDIP-8 package if through-hole mounting is required. Verify that the output drive capability meets load requirements, as it differs from bipolar versions.

Programmable Timers And Oscillators Part Context

The LMC555 belongs to the LMC555 family of CMOS timers produced by Texas Instruments. This family includes variants such as LMC555CM, LMC555IM, and LMC555CTPX/NOPB in various packages like SOIC, TSSOP, and DSBGA. The LMC555CBP specifically denotes a variant within this lineup, maintaining the core functionality of the industry-standard 555 timer while leveraging CMOS advantages.

Programmable Timers And Oscillators Replacement Considerations

The LMC555CBP is pin-compatible with the LM555 and NE555 timers. When replacing these bipolar versions, account for differences in output current drive and supply current characteristics. Ensure the replacement part number matches the required package and temperature grade.
