SN74LS90DE4

Counter Dividers Overview

The SN74LS90DE4 is a single-decade counter integrated circuit manufactured by Texas Instruments, belonging to the SN74LS series. It features a 14-pin SOIC surface-mount package and operates within a supply voltage range of 4.75 V to 5.25 V. The device supports asynchronous reset and preset functions with an up-counting direction. It is rated for operation between 0°C and 70°C. Maximum clock frequencies are specified at 32 MHz and 16 MHz depending on configuration.

Counter Dividers Feature Summary

• Integrates a decade counting function within a compact surface-mount package
• Supports asynchronous reset and preset operations for flexible state control
• Operates reliably across standard commercial temperature ranges

Counter Dividers Applications

• Digital frequency division circuits
• Decimal counting systems in digital logic designs
• Timing sequence generation modules

Counter Dividers Procurement Notes

Verify the specific DE4 suffix indicates lead-free compliance and RoHS certification status against current manufacturer documentation. Confirm the SOIC-14 package dimensions match your PCB footprint requirements. Ensure the operating environment stays within the specified 0°C to 70°C thermal limits for reliable performance.

Counter Dividers Selection Notes

Select this component when a single-channel decimal counter is required in a surface-mount design. It serves as a direct replacement for the non-E4 variant if environmental compliance is mandatory. Consider the SN74LS90N for through-hole applications or the SN74LS390NE4 if dual counters are needed.

Counter Dividers Part Context

This part belongs to the Texas Instruments SN74LS9x family of counters. It shares functional similarities with the SN74LS90 but includes the E4 suffix denoting specific manufacturing and environmental attributes. It is distinct from binary counters like the SN74LS93 or dual-counter variants such as the SN74LS390.

Counter Dividers Replacement Considerations

The SN74LS90D is the primary equivalent without the environmental suffix. For dual-counter functionality, consider the SN74LS390NE4. Through-hole alternatives include the SN74LS90N.
