CY74FCT16823ETPVCT

Overview

The CY74FCT16823ETPVCT is a dual 9-bit bus driver from the FCT logic series, manufactured by Texas Instruments. It features true outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 56-pin TSSOP package (PDSO56) and supports an operating temperature range from -40°C to +85°C. It provides high drive capability with low input capacitance, suitable for high-speed digital applications requiring reliable signal transmission.

Feature Summary

• Dual 9-bit configuration providing 18 total channels for data bus expansion
• True output polarity ensures non-inverted signal transmission
• Compatible with TTL input levels for broad interface integration
• Low input capacitance design minimizes loading effects on driving sources

Applications

• High-speed data bus drivers in computing systems
• Memory buffer interfaces in embedded controllers
• Signal distribution in industrial communication networks
• Peripheral interface circuits requiring high fan-out

Procurement Notes

Verify the exact suffix ETPVCT against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as per the latest regulatory documentation. Ensure the source is an authorized distributor to guarantee component authenticity and traceability. Check for any specific handling requirements related to moisture sensitivity level indicated in the datasheet.

Selection Notes

Select this component when a dual 9-bit non-inverting driver is required for 5V logic systems. Compare propagation delay specifications against system timing constraints. Evaluate pin compatibility if replacing legacy parts. Consider the TSSOP-56 footprint for PCB layout constraints. Verify that the input voltage levels match the preceding stage's output characteristics.

Part Context

This part belongs to the FCT (Fast CMOS Technology) family, designed for high-speed operation with CMOS power consumption. It serves as a bridge between low-voltage logic and higher-current loads. The CY74FCT16823 variant specifically offers dual 9-bit buffering, distinguishing it from single-bit or octal variants in the same series.

Replacement Considerations

Check for direct cross-references such as the 74FCT16823 series equivalents. Verify pin-to-pin compatibility before substitution. Ensure the replacement maintains the same voltage range and package dimensions. Consult the manufacturer's obsolescence notices for lifecycle status.
