74HC40103DB,118

Counter Dividers Overview

The Nexperia 74HC40103DB,118 is an 8-bit synchronous binary down counter housed in a 16-lead SSOP plastic shrink small outline package (SOT338-1). It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features asynchronous master reset and preset capabilities alongside synchronous preset functionality. It includes terminal enable and count outputs for cascading applications.

Counter Dividers Feature Summary

• Supports both synchronous and asynchronous preset operations for flexible data loading
• Includes clamp diodes on inputs to allow interfacing with voltages exceeding VCC using current limiting resistors
• Provides high electrostatic discharge protection exceeding 2000 V under the Human Body Model standard

Counter Dividers Applications

• Divide-by-n counters
• Programmable timers
• Interrupt timers
• Cycle or program counters

Counter Dividers Procurement Notes

Verify the specific ordering suffix '118' against official Nexperia documentation to confirm reel packaging specifications and tape dimensions. Ensure the SSOP16 package variant matches the required board space constraints. Confirm compliance with RoHS directives and REACH regulations prior to final procurement decisions.

Counter Dividers Selection Notes

Select this component when an 8-bit synchronous down counting function is required with low power dissipation characteristics. The wide operating temperature range makes it suitable for industrial environments. Consider the SSOP16 package if space efficiency is prioritized over the standard SO16 footprint.

Counter Dividers Part Context

This part belongs to the 74HC logic family, which utilizes CMOS technology for low power consumption and high noise immunity. The 74HC40103 specifically provides an 8-bit counting capability that can be expanded through cascading terminals. It adheres to JEDEC standard no. 7A for CMOS input levels and performance metrics.

Counter Dividers Replacement Considerations

The 74HC40103D is available in an SO16 package offering identical electrical characteristics but a different physical footprint. The 74HC40103PW utilizes a TSSOP16 package. Verify pin compatibility and thermal derating requirements when substituting between these package types.
