CD4518BPWE4

Counter Dividers Overview

The CD4518BPWE4 is a dual synchronous up-counter from Texas Instruments, designed for CMOS technology. It integrates two independent BCD (Binary-Coded Decimal) counters within a single package. Each counter features a clock input and an enable input to control counting operations synchronously. The device operates with a wide supply voltage range, ensuring compatibility with various digital logic systems. It provides parallel load capability and ripple carry output for cascading multiple units to achieve higher modulus counts. The component is housed in a TSSOP-16 package, suitable for surface-mount applications requiring compact design solutions.

Counter Dividers Feature Summary

Counter Dividers Procurement Notes

Verify the specific suffix 'E4' against official Texas Instruments documentation to confirm environmental compliance and packaging details. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design. Cross-reference with the latest datasheet revision to avoid discrepancies in pin assignments or operating conditions. Confirm availability through authorized distributors only.

Counter Dividers Selection Notes

Select this component when dual independent BCD counting is required in a space-constrained design. Consider the synchronous nature of the counters for timing-critical applications where glitch-free operation is essential. Evaluate the supply voltage requirements against your system's power rails. Assess the need for parallel loading versus serial shifting based on interface constraints.

Counter Dividers Part Context

The CD4500 series represents a family of CMOS logic devices widely used in consumer electronics and industrial controls. The CD4518 specifically addresses the need for decimal counting in digital systems. As a member of this series, it benefits from established reliability and broad ecosystem support. Its CMOS construction offers low power consumption compared to older TTL counterparts, making it suitable for battery-operated devices.

Counter Dividers Replacement Considerations

Check for direct pin-compatible alternatives such as the CD4518BE or other variants within the same family. Verify that any substitute maintains identical logical functionality and electrical characteristics. Ensure the replacement package type matches your PCB footprint if physical interchangeability is required.
