CD4536BPWR

Overview

The CD4536BPWR is a CMOS programmable timer manufactured by Texas Instruments, belonging to the CD4536B series. It features a single internal timer housed in a TSSOP-16 surface-mount package. The device operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55°C to +125°C. Key electrical specifications include a maximum propagation delay of 8 µs, a quiescent supply current of 300 µA, and output currents of 4 mA for both high and low states. Power dissipation is rated at 500 mW.

Feature Summary

• CMOS programmable timer with one internal timer circuit
• Wide supply voltage operation from 3 V to 18 V
• Extended industrial temperature range (-55°C to +125°C)
• TSSOP-16 surface-mount packaging

Applications

• Clock generation circuits
• Pulse width modulation systems
• Timing control logic

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and compliance status. The 'WR' suffix indicates reel packaging. Confirm RoHS compliance details through official documentation before procurement.

Selection Notes

Select this component when a single programmable timer with wide voltage tolerance is required. Ensure the design accommodates the 8 µs maximum propagation delay and 300 µA standby current. Verify that the TSSOP-16 footprint matches the PCB layout requirements.

Part Context

This part is part of the CD4536B family of CMOS programmable timers. It shares core electrical characteristics with variants such as CD4536BPW (tube packaging) and CD4536BDWR (SOIC-16 packaging). The primary distinction lies in the physical package and shipping format.

Replacement Considerations

CD4536BPW offers identical electrical performance in a tube package. CD4536BDWR provides the same functionality in an SOIC-16 package. Verify pinout compatibility and thermal requirements when substituting.
