CD4536BEG4

Overview

The CD4536BEG4 is a CMOS programmable timer manufactured by Texas Instruments, belonging to the CD4536B series. It integrates two independent timers within a single 16-pin package. The device supports a supply voltage range of 3 V to 18 V and operates across an extended temperature range from -55 °C to +125 °C. Key electrical parameters include a maximum propagation delay of 8 µs, a working supply current of 300 µA, and output drive capabilities of 4 mA for both high and low states. The component is housed in a TSSOP-16 surface-mount package.

Feature Summary

• Dual independent programmable timers integrated in a single 16-pin TSSOP package
• Wide operating voltage range from 3 V to 18 V
• Extended industrial temperature range spanning -55 °C to +125 °C
• Low power consumption with a typical supply current of 300 µA

Applications

• Precision timing circuits requiring dual timer functionality
• Industrial control systems operating in extreme temperatures
• Battery-powered devices due to low quiescent current
• Frequency division and pulse generation applications

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's datasheet to confirm RoHS compliance status and pinout compatibility. Ensure the TSSOP-16 footprint matches the design layout. Confirm availability through authorized distributors as lead times may vary based on production cycles.

Selection Notes

Select the CD4536BEG4 when dual timer functionality is required in a compact surface-mount form factor. Compare against the PDIP-16 variant (CD4536BE) if through-hole mounting is necessary. Verify that the 8 µs propagation delay meets the timing precision requirements of the target application.

Part Context

The CD4536BEG4 is part of the Texas Instruments CD4536B family of CMOS programmable timers. The 'G4' suffix typically indicates Green/RoHS-compliant manufacturing. This component serves as a versatile alternative to discrete timer solutions, offering integrated frequency dividers and clock generators within a standard 16-pin interface.

Replacement Considerations

The CD4536BPWRG4 is a verified equivalent offering identical electrical specifications in a TSSOP-16 package. The CD4536BE provides the same functionality in a PDIP-16 through-hole package. Cross-reference pinouts before substitution.
