CD74LPT541AQM

Overview

The CD74LPT541AQM is an 8-bit bus driver from the LPT series manufactured by Harris Corporation. It features true output polarity and a 3-state output configuration with dual output enable controls. The device operates within a temperature range of -40°C to 85°C and utilizes a 20-pin SOP package. Key electrical specifications include a maximum output current of 0.024 A, a load capacitance of 50 pF, and CMOS logic technology.

Feature Summary

• Dual output enable control for flexible signal management
• Three-state output capability for bus line isolation
• CMOS construction ensuring low power consumption

Applications

• Data bus buffering in digital systems
• Signal direction control in communication interfaces
• Memory address/data bus drivers

Procurement Notes

Verify the specific suffix 'AQM' against official Harris or Microchip documentation to confirm the exact package type (QSOP/SSOP) and temperature grade. Ensure compatibility with existing board layouts regarding pin definitions and thermal requirements before procurement.

Selection Notes

Select this component when an 8-bit non-inverting buffer with tri-state outputs is required. The LPT series offers specific voltage and speed characteristics distinct from standard HC or HCT families. Confirm that the dual enable feature meets system control logic requirements.

Part Context

This part belongs to the Harris 74LPT logic family, designed for low-power applications. It serves as a direct replacement for similar 8-bit bus drivers in legacy designs. The manufacturer has transitioned through acquisitions, so datasheet versions may vary.

Replacement Considerations

Check for equivalents such as the CD74LPT541AM. Verify pinout compatibility and electrical parameters against the target application requirements before substituting.
