SN74AUC16245GQLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC16245GQLR is a 16-bit (dual-octal) noninverting bus transceiver from the Widebus family, designed for asynchronous communication between data buses. It operates at VCC levels from 0.8 V to 2.7 V, optimized for 1.65 V to 1.95 V applications. The device features Ioff support for partial-power-down mode and allows bidirectional data transmission controlled by DIR and OE inputs. It provides sub-1-V operability with a maximum propagation delay of 2 ns at 1.8 V. Packaged in a 56-pin Microstar Junior BGA, it ensures low power consumption and robust ESD protection.

• Enables bidirectional data flow between A and B buses through dedicated direction-control and output-enable logic

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication interfaces between data buses
• Mixed-mode signal routing requiring voltage level translation
• Portable electronics utilizing low-voltage power supplies

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific GQL package designation against the datasheet ordering information to ensure correct pinout compatibility. Confirm that the operating environment remains within the specified -40°C to 85°C temperature range. Ensure all unused inputs are tied to VCC or GND to maintain proper CMOS logic functionality and prevent undefined states during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes
