CD4536BE

Overview

The CD4536BE is a CMOS programmable timer manufactured by Texas Instruments, belonging to the CD4000B series. It integrates two independent timers within a single 16-pin PDIP package. The device operates on a supply voltage range of 3 V to 18 V and supports a maximum propagation delay of 8 µs. Key electrical specifications include a high-level output current of 4 mA, a low-level output current of 4 mA, and a typical operating supply current of 300 µA. The component is rated for an ambient temperature range from -55 °C to +125 °C, ensuring functionality in industrial environments.

Feature Summary

• Dual independent timer configuration within a single IC
• CMOS technology with low power consumption (300 µA)
• Wide supply voltage operation: 3 V to 18 V
• Industrial temperature range: -55 °C to +125 °C

Applications

• Precision timing circuits requiring dual channels
• Clock generation systems
• Pulse width modulation applications
• Frequency division networks

Procurement Notes

Verify the package type matches the design requirements, as this specific part number denotes the PDIP-16 through-hole variant. Confirm RoHS compliance status via the manufacturer's datasheet or product information page before finalizing procurement. Ensure the ordering suffix corresponds to the tube packaging format associated with the BE designation.

Selection Notes

Select the CD4536BE when dual independent timers are required in a compact form factor. Compare against the CD4536BPWRG4 if surface-mount TSSOP-16 packaging is preferred for automated assembly. Verify that the 4 mA output drive capability meets the load requirements of the connected circuitry without external buffering.

Part Context

This component is part of the Texas Instruments CD4000B series of CMOS logic devices. The CD4536B family provides versatile timing solutions compared to standard fixed-function timers. It serves as a foundational building block for complex digital timing sequences where multiple independent time bases are necessary within a single integrated circuit footprint.

Replacement Considerations

The CD4536BPWRG4 is a verified pin-compatible alternative offering the same functional specifications but housed in a TSSOP-16 surface-mount package. Designers transitioning from DIP to SMD should verify PCB footprint compatibility and thermal management requirements.
