CD4536BNSR

Overview

The CD4536BNSR is a programmable timer integrated circuit manufactured by Texas Instruments, belonging to the CD4536B series. It features a CMOS output type and operates within a supply voltage range of 3 V to 18 V. The device has a maximum propagation delay of 8 us and supports a wide operating temperature range from -55 C to +125 C. It is housed in an SOIC-16 surface-mount package. Key electrical characteristics include high-level and low-level output currents of 4 mA each, with a typical operating supply current of 300 uA. The power dissipation is rated at 500 mW.

Feature Summary

• CMOS Programmable Timer with single internal timer configuration
• Wide supply voltage operation from 3 V to 18 V
• Extended industrial temperature range: -55°C to +125°C
• SOIC-16 surface-mount package for automated assembly

Applications

• Precision timing circuits requiring programmable intervals
• Frequency division and pulse generation systems
• Industrial control logic involving time-based sequencing
• Consumer electronics utilizing standard CMOS logic interfaces

Procurement Notes

Verify the suffix NSR indicates the SOIC-16 tape-and-reel packaging format. Confirm RoHS compliance status through official manufacturer documentation or certified distributor declarations prior to procurement. Ensure the ordering quantity aligns with the standard reel size to avoid partial reel handling issues.

Selection Notes

Select the CD4536BNSR when a surface-mount solution is required for programmable timing applications. Compare against the PDIP-16 variant (CD4536BE) if through-hole mounting is necessary. Verify that the 8 us propagation delay meets system timing requirements. Ensure the 4 mA output drive capability is sufficient for the connected load capacitance and impedance.

Part Context

This component is part of the Texas Instruments CD4500B family of CMOS logic devices. The CD4536B specifically provides versatile timing functions including astable and monostable modes. It serves as a digital alternative to analog timer ICs, offering compatibility with standard CMOS logic families for integration into complex digital systems.

Replacement Considerations

The CD4536BDWR is a direct functional equivalent in the same SOIC-16 package but may differ in tube versus reel packaging specifications. Cross-reference with other manufacturers' MC14536B parts for pin-compatible alternatives, ensuring voltage and temperature ratings match the design constraints.
