74LS468N

Overview

The SN74LS468N is a buffer and driver integrated circuit manufactured by Rochester Electronics, LLC. It belongs to the LS Series of logic components. The device features a single function with eight-bit data width and true output characteristics. It utilizes TTL technology and is housed in a PDIP20 plastic dual in-line package containing twenty terminals. The component operates within a commercial temperature range, with a maximum operating temperature of 70 °C. The package body material is specified as plastic/epoxy.

Feature Summary

• Provides eight-bit buffering and driving capabilities for digital signals
• Features true output configuration for direct signal transmission
• Utilizes Low-power Schottky (LS) series technology for standard TTL compatibility

Applications

• Digital signal buffering in microprocessor systems
• Interface driving between logic families
• Data bus isolation and strengthening

Procurement Notes

Verify the manufacturer designation as Rochester Electronics, LLC, which acts as an authorized distributor of original factory parts rather than the original design manufacturer. Confirm the specific package type is PDIP20 and that the component meets commercial grade specifications. Ensure the part number matches exactly to avoid confusion with similar buffer variants.

Selection Notes

Select this component when an eight-bit buffer with true output is required for TTL-based designs. The LS series offers a balance of speed and power consumption suitable for general-purpose digital applications. The PDIP20 package facilitates through-hole mounting on printed circuit boards. Verify that the system voltage and current requirements align with standard LS series specifications.

Part Context

Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find semiconductors. They provide lifecycle support for components no longer actively produced by original manufacturers. This part represents a continuation of availability for legacy logic circuits used in existing industrial and commercial equipment maintenance.

Replacement Considerations

Direct substitutes include other SN74LS468 variants from different manufacturers if pin-compatible. Generic equivalents such as the DM74LS468 or MC74LS468 may be considered provided electrical parameters match. Always verify package dimensions and thermal characteristics before substitution.
