74FCT162245ATPVCT

Overview

The Cypress Semiconductor Corp 74FCT162245ATPVCT is a high-speed, low-power bus transceiver belonging to the 74FCT logic series. It integrates two independent 8-bit bidirectional data paths within a single package. The device operates with a supply voltage range of 4.5 V to 5.5 V and features balanced output drivers capable of sourcing and sinking 24 mA. It utilizes a 48-pin Thin Shrink Small Outline Package (TSSOP) with a standard pitch. The component supports TTL input levels and provides true output polarity. Typical propagation delay is specified at 3.5 ns under a 50 pF load condition, ensuring efficient signal transmission in digital systems.

Feature Summary

• Integrates dual 8-bit bidirectional bus transceivers for compact system design
• Features balanced ±24mA output drivers to reduce system switching noise
• Supports live insertion via power-off disable functionality on outputs
• Operates with TTL-compatible input levels and true output polarity

Applications

• High-speed data bus interfaces in computing systems
• Memory bus bridging applications requiring balanced drive strength
• Digital signal routing in industrial control equipment

Procurement Notes

Verify the exact suffix 'TPVCT' against official Cypress documentation to confirm package type, temperature grade, and tape-and-reel specifications. Ensure compatibility with 5V logic families when integrating into existing circuit designs. Cross-reference manufacturer part numbers as corporate structures have changed since the original IDT acquisition.

Selection Notes

Select this component when dual 8-bit isolation is required with balanced current drive capabilities. The TSSOP-48 package offers a space-efficient solution compared to wider SSOP variants. Consider the specific propagation delay requirements and ensure the 5V supply rail stability meets the 4.5V to 5.5V operating range for reliable performance.

Part Context

This device is part of the broader 74FCT family of fast CMOS logic components originally developed by Integrated Device Technology (IDT). Following Cypress Semiconductor's acquisition of IDT, these products are managed under the Cypress portfolio. The 74FCT162245 variant specifically addresses applications needing moderate speed with reduced ground bounce through balanced driver architecture.

Replacement Considerations

Direct replacements include the PI74FCT162245ATV from Diodes Incorporated, which shares identical logical functions and pinout. Other compatible alternatives within the same family may include variations with different suffixes indicating distinct packaging or temperature ranges, provided electrical characteristics remain consistent.
