CY74FCT162245TPVCT

Overview

The CY74FCT162245TPVCT is a 16-bit bus transceiver manufactured by Texas Instruments. It features non-inverting logic with three-state outputs, designed for surface-mount applications in SSOP-48 packages. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. It provides high drive capability with low-level output currents up to 24 mA and high-level output currents up to -24 mA. The component ensures reliable data transfer across wide buses with propagation delays typically around 4.6 ns at 5 V.

Feature Summary

• Provides 16-bit bidirectional data transmission via non-inverting bus transceiver architecture
• Features three-state outputs to facilitate direct connection to system buses without additional drivers
• Supports TTL-compatible input and output voltage levels for broad interface compatibility

Applications

• Wide bus architectures requiring 16-bit data throughput
• Memory mapping systems utilizing bus transceivers
• Control circuits interfacing microprocessors with peripheral devices

Procurement Notes

Verify the specific suffix TPVCT indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SSOP-48 footprint matches the target PCB design constraints. Check for obsolescence notices as this component family may have lifecycle restrictions.

Selection Notes

Select this component for designs requiring 16-bit width rather than standard 8-bit transceivers. The FCT logic series offers speed advantages over older LS families while maintaining CMOS power efficiency. Verify that the 4.5 V to 5.5 V operating range aligns with the system power supply. Consider the SSOP-48 package size relative to available board space.

Part Context

This part belongs to the Texas Instruments FCT (Fast CMOS) logic family, which bridges the performance gap between standard CMOS and bipolar technologies. The 162245 designation specifically identifies it as a 16-bit version of the widely used 245 octal transceiver. It serves as a critical interface element in digital systems requiring expanded bus widths.

Replacement Considerations

Direct substitutes include other 16-bit FCT bus transceivers such as the CY74FCT162245ATPC or CY74FCT162245ATQCT, differing primarily in package type or reel configuration. Cross-reference pinouts and electrical characteristics to ensure functional equivalence before substitution.
