CY54FCT245CTLMB

Overview

The CY54FCT245CTLMB is a non-inverting bus transceiver from the FCT series, manufactured by Cypress Semiconductor Corp. It features one element with eight bits per element and provides three-state outputs. The device utilizes a 20-LCCC package measuring 8.89x8.89 mm. It operates within a voltage range of 4.75 V to 5.25 V and supports temperatures from -40 °C to +85 °C. Propagation delay is 4.6 ns at 5 V with 50 pF load. Maximum output currents are -32 mA for high level and 64 mA for low level.

Feature Summary

• Provides non-inverting data transmission across an eight-bit wide bus interface.
• Features three-state outputs to facilitate multiple driver connections on shared lines.
• Supports live insertion through power-off disable functionality.

Applications

• High-performance memory mapping systems
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix CTLMB confirms the 20-LCCC ceramic package and lead-free status. Ensure the component matches the active product status listed in official Cypress documentation. Confirm moisture sensitivity level 1 classification for standard handling requirements during assembly processes.

Selection Notes

Select this component when a non-inverting transceiver with high drive capability is required for 5V logic interfaces. The FCT series offers compatibility with TTL inputs while maintaining CMOS performance characteristics. Consider the LCCC package constraints for PCB layout and thermal management in dense designs.

Part Context

This part belongs to the FCT (Fast CMOS) logic family, designed for high-speed applications. Cypress Semiconductor developed these components to bridge the gap between standard CMOS and ECL speeds. The CY54 prefix indicates military-grade temperature range availability within the broader product line.

Replacement Considerations

The CY74FCT245ATQCT is a similar Texas Instruments bus transceiver in SSOP packaging. Verify pinout compatibility and package dimensions before substitution. Functional equivalence exists but physical integration requires adapter or redesign considerations.
