SN74LS293D

Counter Dividers Overview

The SN74LS293D is a four-bit binary counter integrated circuit manufactured by onsemi, belonging to the LS logic family. 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 up-counting sequences and functions reliably across an operating temperature range from 0°C to +70°C. Designed for through-hole or surface-mount assembly depending on variant, it provides standard TTL-compatible outputs suitable for digital counting applications.

Counter Dividers Feature Summary

• Four-bit binary counting capability with up-counting sequence
• Schottky TTL technology for high-speed operation
• Standard 14-pin small outline package configuration
• Compatible with standard TTL logic families

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting systems
• Timing control logic
• Event counting applications

Counter Dividers Procurement Notes

Verify the manufacturer designation matches onsemi specifications rather than Texas Instruments variants. Confirm the suffix indicates the correct SOIC package type. Ensure RoHS compliance status aligns with project requirements. Check that the logic family corresponds to Low-power Schottky characteristics. Validate operating temperature range meets environmental constraints.

Counter Dividers Selection Notes

Select this component when a four-bit binary counter with Schottky TTL speed is required in a surface-mount format. Consider the 14-pin SOIC footprint for PCB layout compatibility. Evaluate the 4.75 V to 5.25 V supply requirement against system power rails. Assess the commercial temperature range suitability for the intended environment.

Counter Dividers Part Context

This part belongs to the SN74LS293 series of binary counters. It shares functional similarities with other LS-family logic devices but offers specific pinout and performance characteristics defined by onsemi. The D suffix typically denotes the SOIC package variant within this product line.
