SN74AUC245ZQNR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC245ZQNR is an octal bus transceiver from the Texas Instruments 74AUC series, designed for low-voltage digital applications. It operates within a supply voltage range of 0.8 V to 2.7 V and features three-state outputs. The device provides eight non-inverting channels with a propagation delay of 1.4 ns at typical conditions. It supports CMOS input and output levels, delivering a low-level output current of 9 mA and a high-level output current of -9 mA. Packaged in a 20-VFBGA (Microstar Junior) format, it functions reliably across an industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ZQNR indicates automotive-grade qualification requirements distinct from standard commercial variants. Confirm package dimensions against the Microstar Junior footprint specifications during layout. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the manufacturer's latest datasheet revision to validate electrical characteristics before final integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-density interconnects with strict power constraints. The VFBGA package suits space-constrained printed circuit board layouts. Compare propagation delays against system clock speeds to ensure timing compliance. Evaluate thermal dissipation capabilities relative to the ambient operating environment and enclosure design parameters.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74AUC family, which focuses on advanced ultra-low voltage CMOS technology. The AUC series offers improved speed-to-power ratios compared to legacy 74HC or 74HCT counterparts. The ZQNR designation specifically identifies the automotive grade variant within the broader SN74AUC245 product line, ensuring reliability under rigorous environmental stress conditions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include the commercial grade SN74AUC245RGYR and SN74AUC245GQNR. Verify that alternative parts meet the same automotive qualification standards if the application requires ZQNR-specific reliability certifications. Check for any differences in packaging materials or lead finish compatibility.
