QS74FCT2245ATZ

Buffers, Drivers, Receivers, Transceivers Overview

The QS74FCT2245ATZ is an octal bus transceiver from the FCT logic series, manufactured by Quality Semiconductor. It features a non-inverting design with three-state outputs and TTL-compatible input and output levels. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 4.6 ns. It provides a low-level output current of 12 mA and a high-level output current of -15 mA. The component is housed in a 20-pin SOIC package and functions across a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as Quality Semiconductor, distinct from Texas Instruments or Cypress variants. Confirm the specific suffix 'ATZ' corresponds to the SOIC-20 package and industrial temperature rating. Ensure compatibility with existing FCT-series logic families during integration. Check for obsolescence status as some related Renesas parts are marked end-of-life.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal, non-inverting transceiver with FCT speed characteristics is required. It is suitable for applications needing TTL-compatible I/O with three-state bus driving capabilities. Consider the SOIC-20 package constraints and the specific current drive requirements of 12 mA sink and 15 mA source. Verify that the operating voltage range aligns with the system's 5V power supply tolerance.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the FCT (Fast CMOS) logic family, designed for high-speed digital applications. It serves as a standard solution for buffering and directionally controlling eight-bit data paths. The device complements other FCT transceivers like the QS74FCT162245, offering a single-function octal configuration rather than dual four-bit sections.
