CD74LPT245AQM

Overview

The CD74LPT245AQM is an 8-bit bus transceiver from the LPT series, manufactured by Harris Corporation. It features non-inverting data transmission with three-state outputs and bidirectional direction control. The device operates within a temperature range of -40°C to 85°C and utilizes a 20-pin SSOP package. Key electrical specifications include a maximum output current (Iol) of 0.024 A and a load capacitance (CL) of 50 pF. It is designed for CMOS logic applications requiring reliable data transfer across two ports.

Feature Summary

• Bidirectional data transfer capability with direction control
• Three-state outputs for efficient bus line management
• Non-inverting signal transmission for accurate data integrity

Applications

• High-speed data handling in digital systems
• Bus-oriented memory and interface circuits
• ControlSystem configurations requiring FPGA integration

Procurement Notes

Verify component authenticity through official Harris Corporation channels or authorized distributors. Confirm package type matches the 20-SSOP specification. Check RoHS compliance status as indicated in documentation. Ensure operating temperature ranges align with system requirements. Validate part number suffixes against manufacturer datasheets to confirm functional equivalence.

Selection Notes

Select this component for applications requiring 8-bit bidirectional data transfer with low power consumption. Consider the LPT series characteristics for compatibility with existing CMOS logic families. Evaluate thermal performance within the specified -40°C to 85°C range. Assess pin count and package dimensions for PCB layout constraints. Verify interface requirements match the non-inverting transceiver functionality.

Part Context

This component belongs to the Harris Corporation LPT series of logic devices, specifically designed for bus driver and transceiver applications. It shares architectural similarities with other members like the CD74LPT244QM but offers 8-bit width compared to 4-bit variants. The device supports standard CMOS logic levels and is intended for commercial and industrial environments requiring reliable data routing.

Replacement Considerations

Direct substitutes may include other 8-bit bidirectional transceivers from compatible manufacturers. Verify pinout compatibility and electrical parameters before substitution. Consider equivalent parts from Texas Instruments or NXP if Harris supply is unavailable. Ensure voltage levels and package types match the original design requirements.
