74FCT162501ATPACT

Overview

The CY74FCT162501ATPACT is an 18-bit universal bus transceiver manufactured by Cypress Semiconductor. It operates on a single 4.5 V to 5.5 V power supply and supports a wide operating temperature range of -40°C to 85°C. The device features balanced drive outputs capable of sourcing and sinking 24 mA. It is housed in a 56-pin Thin Shrink Small Outline Package (TSSOP) designed for surface mount technology, ensuring efficient signal transmission for high-speed digital applications.

Feature Summary

• Provides 18-bit bidirectional data path capability for universal bus interfacing
• Delivers balanced 24 mA drive strength for reliable signal integrity
• Supports operation across extended industrial temperature ranges

Applications

• High-speed data bus interfaces
• Memory bus architectures
• General-purpose logic level translation

Procurement Notes

Verify the exact suffix against official Cypress documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts and voltage levels before procurement. Confirm RoHS compliance status through current manufacturer declarations.

Selection Notes

Select this component when an 18-bit width is required for bus expansion or interface bridging. Consider the 56-TSSOP footprint for space-constrained designs requiring surface mount assembly. Evaluate the 24 mA drive capability against load requirements to ensure adequate performance margins.

Part Context

This part belongs to the 74FCT logic family, known for CMOS speed with TTL-compatible inputs. It serves as a bridge between different logic families or system segments requiring robust data transfer capabilities within standard 5V logic environments.

Replacement Considerations

Check for pin-compatible alternatives within the same FCT family that may offer updated packaging or specific temperature variants. Verify electrical equivalence regarding drive strength and input thresholds before substitution.
