MC14541BDTR2

Programmable Timers And Oscillators Overview

The MC14541BDTR2G is a programmable timer and oscillator manufactured by onsemi, housed in a TSSOP-14 surface-mount package. It integrates a 16-stage binary counter, an RC oscillator, and power-on reset logic. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc. Key electrical parameters include a maximum propagation delay of 10.5 µs (clock to Q at 2^8 output) and a typical quiescent current of 15 µA at 15 V with auto-reset disabled. Output drive capabilities provide a source current of -16.3 mA and a sink current of 19.3 mA at 15 V.

Programmable Timers And Oscillators Feature Summary

• Integrates a 16-stage binary counter with selectable outputs at 2^8, 2^10, 2^13, or 2^16 stages via Mode A/B inputs.
• Features a built-in low-power RC oscillator with external timing components, or supports an external clock input on Pin 3.
• Includes automatic power-on reset circuitry and an independent external master reset function.
• Offers Q/Q select pin for flexible output logic level configuration after reset.

Programmable Timers And Oscillators Applications

• Digital timer circuits requiring precise single-cycle or recycle mode operation.
• Frequency divider applications utilizing the internal 16-stage counter.
• Systems requiring automatic initialization upon power-up without external reset components.

Programmable Timers And Oscillators Procurement Notes

Verify the ordering suffix 'TR2G' corresponds to the TSSOP-14 package and tape-and-reel shipping format as specified in the manufacturer's ordering information. Confirm RoHS compliance and Pb-Free status through official documentation before procurement.

Programmable Timers And Oscillators Selection Notes

Select this component when a CMOS programmable timer with integrated oscillator functionality is required in a compact TSSOP-14 footprint. Ensure the application voltage remains between 3 V and 18 V and that the load capacitance requirements are met to maintain specified propagation delays.

Programmable Timers And Oscillators Part Context

This part belongs to the MC14541B family of programmable timers. The 'DT' suffix indicates the TSSOP-14 package variant, while 'R2G' denotes the reel packaging and lead-free composition. Other variants include SOIC-14 (D suffix) and SOEIAJ-14 (F suffix).

Programmable Timers And Oscillators Replacement Considerations

The MC14541BFELG is listed as discontinued in the datasheet revision history. Verify compatibility with alternative packages such as the SOIC-14 (MC14541BDR2G) if physical footprint changes are permissible.
