CY74FCT16245CTPACT

Overview

The CY74FCT16245CTPACT is a 16-bit bus transceiver from the FCT series, manufactured by Texas Instruments. It features two functional blocks of 8 bits each with true outputs and 3-state capability. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to +85°C. It utilizes a 48-pin TSSOP package with a 0.240-inch body width. The propagation delay is specified at 7 ns, and it includes direction control functionality.

Feature Summary

• Provides bidirectional data transmission across two independent 8-bit channels
• Features 3-state outputs for effective bus line management
• Incorporates direction control pins to manage signal flow
• Compatible with TTL input levels and CMOS output characteristics

Applications

• High-speed data bus architectures in computing systems
• Memory interface circuits requiring bidirectional transfer
• Industrial control systems with multiple I/O ports
• Communication equipment utilizing parallel data buses

Procurement Notes

Verify the specific suffix 'CTPACT' against the manufacturer's current datasheet to confirm package type, tape-and-reel specifications, and RoHS compliance status. Ensure the component matches the required 48-pin TSSOP form factor and industrial temperature rating before integration into production designs.

Selection Notes

Select this component when designing systems requiring 16-bit wide bidirectional data paths with low propagation delay. It is suitable for applications needing compatibility between TTL inputs and CMOS outputs. Consider the 48-pin TSSOP footprint constraints and the need for external pull-up resistors if driving high-capacitance loads on the bus lines.

Part Context

This part belongs to the Texas Instruments 74FCT logic family, designed for fast CMOS technology. It serves as a standard solution for interfacing microprocessors with memory or peripheral devices. The FCT series is known for its speed and power efficiency compared to older logic families, making it relevant in legacy and mixed-signal system designs.

Replacement Considerations

Check for direct equivalents such as the SN74FCT16245CTPACT or CY74FCT16245ATPACT. Verify pinout compatibility and electrical parameters like propagation delay and drive strength before substituting.
