CD4536BPWRE4

Overview

The CD4536BPWRE4 is a CMOS programmable timer manufactured by Texas Instruments, belonging to the CD4536B series. 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 provides high-level and low-level output currents of 4 mA each. It consumes a typical working power current of 300 µA with a power dissipation rating of 500 mW. This component is housed in a TSSOP-16 surface-mount package.

Feature Summary

• CMOS programmable timer architecture
• Wide supply voltage range: 3 V to 18 V
• Extended industrial temperature range: -55 °C to +125 °C
• TSSOP-16 surface-mount package

Applications

• Timing circuits requiring programmable intervals
• Pulse generation systems
• Clock signal generation for digital logic

Procurement Notes

Verify the specific suffix 'PWRE4' against the manufacturer's datasheet to confirm lead-free status and tape-and-reel packaging specifications. Ensure compatibility with standard TSSOP-16 footprints during PCB layout. Confirm that the required operating voltage and temperature ranges align with the system design constraints before procurement.

Selection Notes

Select this component when a single-channel programmable timer is needed with wide voltage tolerance. Compare against the CD4536BE variant if through-hole mounting is preferred. Verify that the 8 µs propagation delay meets the timing precision requirements of the application. Check for alternative packages if higher pin density or different thermal performance is required.

Part Context

This part is part of the CD4536B family of CMOS programmable timers. It shares functional similarities with other members like the CD4536BPWR but differs in packaging (TSSOP vs. SOIC) and compliance markings (E4 suffix indicating lead-free). It serves as a versatile timing solution within the broader 4000-series CMOS logic ecosystem.

Replacement Considerations

The CD4536BPWR is a direct functional substitute with identical electrical characteristics but may differ in packaging material or compliance markings. Cross-reference with the official TI substitution guide to ensure pinout and parameter equivalence.
