CD74LPT16240ASM

Overview

The CD74LPT16240ASM is an 8-bit bus driver from the LPT series manufactured by Harris Corporation. It features two functional units, each handling four bits with inverted outputs. The device utilizes CMOS technology and operates within a temperature range of -40°C to 85°C. It is housed in a 48-pin SSOP package (SSOP48,.4) with a plastic/epoxy body. Key electrical parameters include a maximum operating frequency of 100 MHz, a load capacitance of 50 pF, and a maximum output current of 0.024 A. The logic type is defined as a bus driver with three-state output characteristics.

Feature Summary

• Inverted output polarity for signal inversion applications
• Three-state output capability for bus line isolation
• Low power consumption inherent to LPT CMOS technology

Applications

• High-speed data bus interfacing
• Memory address/data bus drivers
• Control signal distribution in digital systems

Procurement Notes

Verify component authenticity through manufacturer documentation or authorized channels. Confirm RoHS compliance status, as indicated as non-compliant in available records. Ensure the SSOP48 package matches design requirements. Check for moisture sensitivity level if reflow soldering is planned. Validate that the specific Harris Corporation manufacturing source meets quality standards for the intended application environment.

Selection Notes

Select this component when inverted 8-bit bus driving is required with low power constraints. The LPT series offers speed suitable for general digital interfaces. Compare against other LPT variants if non-inverted outputs are needed. Ensure the 48-pin SSOP footprint fits the PCB layout. Consider thermal management within the specified -40°C to 85°C operational range.

Part Context

This part belongs to the Harris Corporation 74LPT logic family, designed for low-power high-speed operations. It complements other LPT bus transceivers and drivers like the CD74LPT16374ASM. The FCT series offers similar functionality but with different drive strengths. This specific model provides a cost-effective solution for standard digital logic interfacing tasks requiring bus isolation.

FAQ

What is the output polarity of the CD74LPT16240ASM?

The outputs are inverted relative to the inputs.

Does this device support bidirectional data transfer?

No, it is a unidirectional bus driver; bidirectional transfer requires a transceiver like the CD74LPT16245SM.
