CD74LPT16244ASM

Overview

The CD74LPT16244ASM is an octal bus driver manufactured by Harris Corporation, belonging to the LPT logic series. It features two independent functions, each handling eight bits of data with true output polarity. The device utilizes CMOS technology and is housed in a 48-terminal plastic dual small-outline package (PDSO48). It supports a maximum operating frequency of 100 MHz at a nominal supply voltage. The outputs are characterized as three-state, capable of driving a load capacitance of 50 pF with a maximum low-level output current of 24 mA. The component operates within a temperature range of -40°C to 85°C.

Feature Summary

• Provides high-speed data buffering for digital systems through dedicated bus driver architecture.
• Integrates three-state output capability to facilitate efficient bus sharing and system isolation.
• Employs CMOS construction to ensure stable signal transmission with defined drive strength.

Applications

• High-speed data bus buffering in computing architectures
• Clock distribution and signal buffering in digital circuits
• Control signal routing in industrial automation systems

Procurement Notes

Verify the manufacturer designation, as Harris Corporation's semiconductor assets were acquired by Texas Instruments. Confirm that the specific part number corresponds to the original Harris production run rather than subsequent TI equivalents. Ensure the package type matches the required 48-pin SSOP footprint and validate the operational temperature range against system requirements before procurement.

Selection Notes

Select this component when designing systems requiring robust octal bus interfacing with moderate speed capabilities up to 100 MHz. The LPT series offers a balance between performance and power consumption suitable for general-purpose digital applications. Consider the 3-state output feature if multiple devices share a common data bus. Verify compatibility with the system's voltage levels and load requirements.

Part Context

This component is part of the broader 74-series logic family, specifically the LPT subset designed for low-power transistor-transistor logic applications. It serves as a fundamental building block for data path management in electronic designs. The device complements other bus transceivers and drivers within the same logical hierarchy, providing standardized interface solutions for legacy and specialized hardware platforms.

Replacement Considerations

Consult official datasheets for cross-reference information regarding equivalent parts from Texas Instruments or other manufacturers. Verify pinout compatibility and electrical specifications before substituting with alternative components to ensure functional integrity.
