CY74FCT162244ATPVC

Overview

The CY74FCT162244ATPVC is an octal buffer and line driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features balanced output drivers with 24 mA sink and source currents, designed to reduce system switching noise. It includes edge-rate control circuits for improved noise characteristics and typical output skew under 250 ps. The component supports Ioff circuitry for partial power-down applications, preventing backflow current when the device is powered off.

Feature Summary

• Balanced output drivers provide 24 mA drive capability to minimize ground bounce and switching noise.
• Ioff support enables partial power-down mode operation by disabling outputs to prevent backflow.
• Edge-rate control circuits are integrated to significantly improve signal integrity and noise performance.

Applications

• Memory bus interface driving
• Clock distribution networks
• High-speed low-power bus interfaces

Procurement Notes

Verify the specific suffix 'ATPVC' against the manufacturer's latest datasheet to confirm package type (TSSOP-48) and temperature grade. Ensure compatibility with existing PCB footprints and verify that the Ioff functionality aligns with the target system's power management requirements during standby states.

Selection Notes

Select this component for designs requiring robust 24 mA drive strength on 8-bit buses with strict noise constraints. The balanced output architecture reduces the need for external termination resistors compared to standard drivers. Consider the TSSOP-48 package dimensions for board space limitations and ensure the 4.5 V to 5.5 V operating range matches the system power rails.

Part Context

This part belongs to the FCT logic family, which combines CMOS density with TTL-compatible speeds. The CY74FCT162244 variant specifically offers balanced outputs, distinguishing it from the standard CY74FCT162244 which has higher drive currents but less controlled edge rates. It serves as a high-performance solution for mid-density digital systems requiring reliable data transmission.

Replacement Considerations

Publicly confirmed substitutes include the Renesas Electronics Corporation 74FCT162244ATPAG8. Verify pinout compatibility and electrical specifications before substitution.
