CD74FCT16245CTMT

Overview

The CD74FCT16245CTMT is a non-inverting dual bus transceiver from the FCT series, manufactured by Harris Corporation. It integrates two independent 8-bit bidirectional elements within a single package. The device operates on a nominal supply voltage of 5 V, with an acceptable range between 4.5 V and 5.5 V. It utilizes a 48-pin TSSOP plastic surface-mount package. Key electrical characteristics include a propagation delay of 4.6 ns at nominal supply and a load capacitance rating of 50 pF. The outputs provide 3-state capability to facilitate efficient data transfer across system buses.

Feature Summary

• Dual 8-bit bidirectional configuration for flexible data routing
• Non-inverting signal transmission logic
• 3-state output design enabling multi-driver bus environments
• CMOS construction supporting high-speed digital applications

Applications

• High-performance microprocessor systems
• Memory modules requiring bidirectional data transfer
• Control circuits in industrial automation
• Communication interfaces in computing hardware

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities such as Renesas Electronics, as corporate acquisitions may affect branding on legacy components. Confirm the specific package variant matches the 48-pin TSSOP form factor. Ensure the component meets the required operating temperature range of -40 °C to 85 °C for your specific application environment. Cross-reference datasheets to confirm pinout compatibility if integrating into existing designs.

Selection Notes

Select this component when a non-inverting dual 8-bit transceiver is required for CMOS logic families. It is suitable for applications demanding low propagation delay and high drive capability. Consider the 48-pin TSSOP package constraints regarding PCB space and thermal management. Ensure the system voltage aligns with the 4.5 V to 5.5 V operational window. Evaluate the 50 pF load capacitance limit against the connected bus lines to maintain signal integrity.

Part Context

This part belongs to the FCT (Fast CMOS) logic family, designed for high-speed digital switching applications. It serves as a bridge between different logic levels or segments within a complex electronic system. The dual-element structure allows for simultaneous handling of two separate 8-bit data paths, reducing component count compared to using single-bit transceivers. It represents a standard solution for bidirectional data flow in mid-1990s to early-2000s electronics architectures.

Replacement Considerations

Check for direct equivalents from Harris Corporation or Renesas Electronics that share the same FCT specification and pinout. Verify functional compatibility with other dual 8-bit non-inverting bus transceivers in the market. Ensure any substitute maintains the 48-pin TSSOP package dimensions and electrical parameters such as propagation delay and supply voltage range.
