SN74LS90DG4

Counter Dividers Overview

The SN74LS90DG4 is a single-decade counter integrated circuit manufactured by Texas Instruments. It belongs to the 74LS logic family and utilizes a 14-SOIC surface-mount package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to 70°C. It features asynchronous reset and preset capabilities, with a maximum clock frequency of 32 MHz.

Counter Dividers Feature Summary

• Integrates a decade counting function within a compact surface-mount package
• Supports asynchronous reset and preset operations for flexible control
• Compatible with standard 5V logic systems via the LS series

Counter Dividers Applications

• Digital timing circuits requiring decimal counting sequences
• Frequency division applications in electronic systems
• General-purpose digital logic designs utilizing TTL-compatible components

Counter Dividers Procurement Notes

Verify the specific suffix 'DG4' against official manufacturer documentation to confirm RoHS compliance status and exact pinout configuration. Ensure the selected component matches the required SOIC-14 package dimensions and thermal characteristics for the target application environment.

Counter Dividers Selection Notes

Select this component when a surface-mount decade counter is required for space-constrained designs. Confirm that the 32 MHz maximum frequency meets the system's timing requirements. Verify compatibility with existing PCB footprints designed for the 14-SOIC package format.

Counter Dividers Part Context

This part is a variant within the broader 74LS90 family, distinguished by its green (RoHS compliant) manufacturing process indicated by the 'G4' suffix. It serves as a surface-mount alternative to through-hole versions like the SN74LS90N, maintaining functional equivalence while adapting to modern assembly techniques.
