74HC193DB,118

Counter Dividers Overview

The 74HC193DB,118 is a synchronous 4-bit binary up/down counter manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 6.0 V and features separate clock inputs for counting up (CPU) and counting down (CPD). The device includes asynchronous parallel load and master reset capabilities. It utilizes CMOS technology for low power dissipation and high noise immunity. The component is housed in an SO16 plastic small outline package (SOT109-1) with 16 leads.

Counter Dividers Feature Summary

• Supports synchronous reversible 4-bit binary counting using distinct clock inputs for up and down operations.
• Features asynchronous parallel load and master reset functions for immediate state control.
• Provides expandability without external logic through dedicated terminal count outputs.

Counter Dividers Applications

• Cascaded multi-stage counter configurations
• Digital timing circuits requiring precise up or down counting sequences
• Frequency division applications

Counter Dividers Procurement Notes

Verify the specific ordering suffix '118' against current manufacturer documentation to confirm availability status. Confirm that the SO16 package variant matches the required PCB footprint. Ensure compliance with RoHS directives and check for any recent discontinuation notices from Nexperia before finalizing procurement plans.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with independent up/down clocking is required. The HC series offers wide voltage compatibility compared to HCT variants. Consider the SO16 package dimensions and thermal characteristics for integration into the target design environment.

Counter Dividers Part Context

This part belongs to the 74HC/HCT logic family, specifically designed for general-purpose digital applications. The 74HC193 variant provides CMOS performance levels. It is distinct from ripple counters like the 74HC393 due to its synchronous operation and dual-clock architecture.

Counter Dividers Replacement Considerations

The 74HCT193DB,118 serves as a functional replacement if TTL-compatible input levels are acceptable. Verify pinout compatibility and ensure the alternative device supports the same operating voltage range and package type.
