SN74LS590D

Counter Dividers Overview

The SN74LS590D is an 8-bit binary counter integrated circuit manufactured by Texas Instruments. It belongs to the LS logic series and features a dedicated input register alongside three-state outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an up-counting sequence. It is housed in a 16-pin SOIC package designed for surface mount technology. The component functions reliably across an operating temperature range from 0°C to +70°C.

Counter Dividers Feature Summary

• Includes an internal input register to isolate data inputs from the counting mechanism
• Provides three-state outputs for direct bus interfacing capabilities
• Supports cascading connections for expanded bit-width applications

Counter Dividers Applications

• Digital frequency division circuits
• Binary event counting systems
• Timing control logic modules

Counter Dividers Procurement Notes

Verify that the specific orderable part number matches the required package style, as the SN74LS590 family includes variants such as SN74LS590N and SN74LS590NSR. Confirm RoHS compliance status and lead finish specifications against project requirements. Ensure the selected variant aligns with the necessary moisture sensitivity level ratings for the intended assembly process.

Counter Dividers Selection Notes

Select this component when an 8-bit synchronous binary count with latched inputs is required. The LS logic family offers specific drive characteristics suitable for standard TTL loads. Consider the SOIC package dimensions for PCB layout constraints. Verify that the operating temperature range meets the environmental conditions of the final application.

Counter Dividers Part Context

This device is part of the broader SN74LS590 product line, which also includes versions like SN74LS590N and SN74LS590NSR. These variants share identical logical functionality but differ in physical packaging and shipping configurations. The SN74LS590D specifically denotes the surface-mount SOIC option within this catalog series.

Counter Dividers Replacement Considerations

Direct functional equivalents include other SN74LS590 variants such as SN74LS590N or SN74LS590NSR, provided the package type difference is accommodated.
