CD74LPT541AM

Overview

The CD74LPT541AM is an eight-bit bus driver from the LPT series manufactured by Harris Corporation. It features true output polarity and operates within a CMOS technology framework housed in a PDSO20 package. The device supports dual output enable control with active-low logic. Electrical specifications include a maximum load capacitance of 50 pF and a maximum output current (Iol) of 0.024 A. It functions as a single-function, two-port component with three-state outputs. The operational temperature range spans from -40 °C to +85 °C.

Feature Summary

• Provides non-inverting buffering for eight-bit data buses
• Features dual independent output enable inputs for precise control
• Supports three-state output configuration for bus sharing

Applications

• High-speed data bus buffering applications
• Memory address/data bus drivers
• Clock distribution circuits requiring high fan-out

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm package marking accuracy against the PDSO20 specification. Ensure supply chain sources provide valid manufacturer traceability for the Harris Corporation part number. Check for potential obsolescence or lifecycle changes given the vintage of the component series.

Selection Notes

Select this component when low-power CMOS performance is required for eight-bit parallel data transmission. The LPT series offers specific electrical characteristics distinct from standard HC or HCT families. Verify that the system voltage levels align with the LPT series requirements rather than assuming standard 5V compatibility without datasheet confirmation.

Part Context

This component belongs to the Harris Corporation CD74LPTxxxyy series of logic integrated circuits. It is functionally related to other octal bus drivers like the CD74HC541 but utilizes Low-Power Schottky or similar proprietary CMOS processes defined by the LPT designation. It serves as a buffer between microprocessors and peripheral devices.
