Counter Dividers datasheet and documents for SN74LS390NS

SN74LS390NS

Counter Dividers Overview

The SN74LS390NS is a dual 4-bit decade and binary counter integrated circuit manufactured by Texas Instruments. It belongs to the 74LS logic series and operates within a supply voltage range of 4.75 V to 5.25 V. The device features asynchronous reset functionality and negative-edge triggered flip-flops. It supports counting rates up to 35 MHz and functions reliably across an operating temperature range of 0°C to 70°C. The component is housed in a 14-pin SOIC package with a width of 0.209 inches (5.30 mm) for surface-mount installation.

Counter Dividers Feature Summary

Integrates two independent 4-bit counters capable of functioning as either decade or binary counters
Utilizes negative-edge triggering for precise clock signal synchronization
Features asynchronous reset inputs for immediate counter initialization

Counter Dividers Applications

Digital frequency division circuits
Timekeeping and digital clock systems
Event counting applications

Counter Dividers Procurement Notes

Verify that the specific part number matches the required 14-pin SOIC surface-mount package configuration. Confirm compliance with RoHS3 standards and ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the manufacturer's datasheet for accurate pinout definitions and electrical characteristics before finalizing procurement specifications.

Counter Dividers Selection Notes

Select this component when a dual counter solution is required in a compact surface-mount format. The LS logic family offers a balance of speed and power consumption suitable for general-purpose digital designs. Ensure the design accommodates the asynchronous nature of the reset signals and the specific voltage requirements of the 74LS series.

Counter Dividers Part Context

This component is part of the broader 74LS390 family, which includes variants such as the SN74LS390N in DIP packaging and the SN74LS393NS in SOIC format. While sharing core logical functionality, the SN74LS390NS specifically denotes the surface-mount variant. It serves as a fundamental building block for sequential logic circuits requiring multiple independent counting stages.
