CY74FCT163500CPVCT

Overview

The CY74FCT163500CPVCT is an 18-bit registered bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features a 48-pin SSOP package designed for surface-mount installation. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. It provides non-inverting data transfer with a maximum propagation delay of 4.6 ns at 5 V under 50 pF load conditions. The component functions across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Provides 18-bit bidirectional data transmission capability through a single integrated circuit
• Integrates registered storage elements to latch data independently of the direction control signal
• Supports high-speed operation with low propagation delay characteristics suitable for system buses

Applications

• High-density memory buffer applications in computer systems
• Clock driver circuits requiring registered output buffering
• Control signal distribution in complex digital logic architectures

Procurement Notes

Verify the specific suffix 'CTPVCT' against the manufacturer's official documentation to confirm pinout compatibility and moisture sensitivity level requirements. Ensure that the ordering information matches the exact package variant and tape-and-reel specifications defined in the current datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when an 18-bit width is required for bus interfacing tasks. The registered nature of the transceiver makes it distinct from unbuffered variants, offering improved timing control. Consider the 48-pin SSOP footprint constraints during PCB layout planning to ensure adequate spacing and thermal management for the specified operating temperature range.

Part Context

This part belongs to the FCT (Fast CMOS Technology) family, which bridges the performance gap between standard TTL and advanced CMOS logic families. The 74FCT163500 specifically addresses the need for wide-bus registered interfaces in legacy and mixed-voltage digital systems, providing robust drive capabilities while maintaining compatibility with standard logic levels.

Replacement Considerations

Consult official substitution lists for equivalent 18-bit registered transceivers. Verify functional compatibility regarding pin assignments and electrical characteristics before replacing the original component.
