CD4536BEE4

Overview

The CD4536BEE4 is a CMOS programmable timer manufactured by Texas Instruments, supplied in a 16-lead plastic dual-in-line (PDIP) 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 with internal oscillator and external timing control
• Wide supply voltage operation: 3 V to 18 V
• Extended industrial temperature range: -55°C to +125°C
• Low power consumption: 300 µA typical supply current

Applications

• Precision timing circuits
• Pulse generation systems
• Frequency division applications

Procurement Notes

Verify the E4 suffix indicates lead-free composition and RoHS compliance per Texas Instruments standards. Confirm the PDIP-16 package type matches the target PCB footprint. Ensure the -55°C to +125°C temperature rating aligns with environmental requirements. Check for active production status and availability through authorized distributors.

Selection Notes

Select the CD4536BEE4 when a single programmable timer with wide voltage tolerance is required. Compare against other CD4536B variants if surface-mount packaging (SOIC, TSSOP) is preferred over through-hole DIP. Verify that the 4 mA output current meets load requirements. Consider the 8 µs propagation delay for timing accuracy constraints.

Part Context

The CD4536BEE4 belongs to the CD4536B family of CMOS programmable timers. It is functionally equivalent to the CD4536BE but includes the E4 suffix denoting lead-free manufacturing and environmental compliance. Other package options include SOIC (DW), TSSOP (PW), and ceramic DIP (F3A).

Replacement Considerations

Direct pin-compatible replacements within the same family include CD4536BE (standard leaded) and CD4536BDW (SOIC package). For military specifications, the CD4536B-MIL variant is available. Surface-mount equivalents are CD4536BPWR (TSSOP) and CD4536BDWR (SOIC).
