CD4541BMTG4

Overview

The CD4541BMTG4 is a CMOS programmable timer manufactured by Texas Instruments, housed in a 14-SOIC surface-mount package. It integrates a 16-stage binary counter, an RC-controlled oscillator, and automatic power-on reset logic. The device operates on a supply voltage range of 3V to 18V and supports frequencies up to 100kHz. Key electrical parameters include a maximum propagation delay of 10500 ns, output currents of ±4 mA, and a quiescent current of 300 µA. It functions as a frequency divider or monostable timer with selectable output modes.

Feature Summary

• Integrated 16-stage binary counter with divide-by-2^N capability
• RC-controlled oscillator supporting DC to 100kHz operation
• Automatic power-on reset circuit for reliable initialization
• Selectable output modes including continuous oscillation and monostable trigger

Applications

• Clock and timing control circuits
• Frequency division applications
• Pulse generation systems
• Long-duration timer implementations

Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS standards when sourcing. Confirm the SOIC-14 package dimensions match PCB footprint requirements. Ensure operating conditions remain within the specified -55°C to +125°C temperature range for industrial reliability.

Selection Notes

Select this component for designs requiring a single-chip solution for programmable timing without external microcontrollers. Compare against through-hole variants like CD4541BE if prototyping on breadboards. Verify that the 100kHz maximum frequency meets the system clock requirements before finalizing the design.

Part Context

This part belongs to the CD4541B family of high-voltage CMOS timers. The 'G4' suffix denotes a specific manufacturing revision compliant with environmental directives. It serves as a direct replacement for standard CD4541BM devices in existing layouts while ensuring regulatory compliance.

Replacement Considerations

CD4541BM is a compatible alternative from Texas Instruments. CD4541BE offers the same functionality in a DIP package for different mounting needs.
