CD4536BPWRG4

Overview

The CD4536BPWRG4 is a CMOS programmable timer manufactured by Texas Instruments, housed in a 16-pin TSSOP package. It operates within a supply voltage range of 3 V to 18 V and supports an extended 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 4 mA for both high and low states. This component belongs to the CD4536B series and is designed for applications requiring precise timing control in industrial or commercial environments.

Feature Summary

• CMOS programmable timer with dual internal oscillators
• Wide supply voltage range: 3 V to 18 V
• Extended operating temperature: -55 °C to +125 °C
• Low power consumption: 300 µA typical supply current

Applications

• Industrial process control timing circuits
• Commercial equipment pulse generation
• General-purpose monostable and astable multivibrator designs

Procurement Notes

Verify RoHS compliance status through official manufacturer documentation before integration. Confirm that the TSSOP-16 footprint matches the PCB layout requirements. Ensure thermal management strategies account for the specified power dissipation limits under maximum load conditions. Cross-reference the G4 suffix with the latest datasheet to confirm lead-free material specifications.

Selection Notes

Select this component when a wide voltage range and extended temperature operation are required. Compare against standard logic families if lower propagation delay is critical, as this device has an 8 µs max delay. Verify that the 4 mA output current meets the load requirements of the connected circuitry without external buffering.

Part Context

This part is a green, lead-free variant of the CD4536BPWR, indicated by the G4 suffix. It belongs to the broader CD4000/CD4500 series of CMOS logic devices. The BPWR designation specifies the TSSOP-16 package and reel packaging format suitable for surface-mount assembly processes.

Replacement Considerations

The CD4536BPWR is the non-green equivalent. For automotive applications, consider the CD74HC4538QPWRG4Q1, which offers faster speeds but requires a lower supply voltage (2 V to 6 V). Direct pin-to-pin replacement with other logic families is not guaranteed due to differing electrical characteristics.
