CD4536BPW

Overview

The CD4536BPW is a CMOS programmable timer manufactured by Texas Instruments, housed in a 16-pin TSSOP surface-mount package. It operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55°C to +125°C. The device features a maximum propagation delay of 8 µs and draws a typical operating supply current of 300 µA. Output drive capabilities include high-level and low-level currents of 4 mA each, with a power dissipation rating of 500 mW.

Feature Summary

• CMOS programmable timer architecture with single internal timer configuration
• Wide supply voltage operation from 3 V to 18 V
• Extended industrial temperature range spanning -55°C to +125°C
• TSSOP-16 surface-mount packaging for compact board integration

Applications

• Precision timing circuits requiring programmable intervals
• Pulse width modulation signal generation
• Frequency division and clock generation systems
• Industrial control logic timing sequences

Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-16 tube packaging variant distinct from reel-based options like 'BPWR'. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure ordering quantities align with the standard tube pack size of 90 units to avoid partial package handling issues.

Selection Notes

Select this component when a surface-mount solution is required for programmable timing applications. Compare against the DIP variant CD4536BE if through-hole mounting is necessary. Verify that the 4 mA output current meets load requirements. Consider the CD4536BPWR alternative if reel or cut-tape packaging is preferred for automated assembly processes.

Part Context

This part belongs to the CD4536B series of CMOS programmable timers. It shares core electrical specifications with other variants such as CD4536BE (PDIP) and CD4536BPWR (TSSOP Reel). The primary distinction lies in the mechanical package type and shipping format, while maintaining identical functional performance and pinout compatibility within the family.

Replacement Considerations

CD4536BE serves as a direct pin-compatible replacement using a PDIP-16 through-hole package. CD4536BPWR offers identical functionality in a TSSOP-16 reel or cut-tape format. CD4536BPWRG4 is also available as a lead-free compliant variant within the same TSSOP-16 footprint.
