CY74FCT16245CTPVC

Overview

The CY74FCT16245CTPVC is a 16-bit bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features two independent 8-bit transceivers with true outputs and 3-state capabilities in a 48-pin TSSOP package. The device operates within a supply voltage range of 4.75V to 5.25V and supports TTL input levels with TTL output levels. It exhibits a propagation delay of 7 ns and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual 8-bit architecture providing two independent bidirectional data paths
• True output polarity for non-inverting signal transmission
• 3-state outputs enabling effective bus line isolation and management

Applications

• High-speed data routing in computing systems
• Memory buffer interfaces in embedded controllers
• Bidirectional data transfer between microprocessors and peripherals

Procurement Notes

Verify the specific suffix 'CTPVC' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the component matches the required 48-pin TSSOP footprint and electrical specifications for your design. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before procurement.

Selection Notes

Select this component when designing systems requiring dual-channel 16-bit data transfer at moderate speeds. The FCT technology offers a balance of speed and drive strength suitable for 5V logic environments. Consider the TSSOP-48 package constraints for PCB layout and thermal management. Verify that the 7 ns propagation delay meets the timing requirements of your specific bus protocol.

Part Context

This device belongs to the CY74FCT245T family of octal bus transceivers, adapted for 16-bit applications. It shares functional similarities with other FCT series components but provides enhanced data throughput through its dual-channel design. The part integrates standard CMOS processes optimized for fast switching speeds while maintaining compatibility with TTL logic families.

Replacement Considerations

Publicly confirmed substitutes include CY74FCT16245TPACR and CY74FCT16245ETPVCT. These alternatives offer similar 16-bit transceiver functionality and may serve as drop-in replacements depending on package availability and specific manufacturing lot requirements.
