SN74AUC16245ZQLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC16245ZQLR is a 16-bit (dual-octal) noninverting bus transceiver from the Texas Instruments Widebus family, designed for asynchronous communication between data buses. It operates at supply voltages ranging from 0.8 V to 2.7 V, with specific optimization for 1.65-V to 1.95-V operation. The device features configurable direction control and output enable inputs to manage data transmission between A and B buses or isolate them. It supports partial-power-down mode via Ioff circuitry to prevent backflow current. Key electrical characteristics include a maximum propagation delay of 2 ns at 1.8 V, low power consumption with a maximum ICC of 20 µA, and ±8-mA output drive capability at 1.8 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact package type and suffix against the official TI ordering information, as the ZQLR designation corresponds to the VFBGA-GQL package variant. Confirm active status and lead times directly with authorized distributors, as availability may fluctuate. Ensure compatibility with your board layout requirements regarding the specific pinout and thermal characteristics of the GQL package before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require high-speed data transfer at low supply voltages near 1.8 V. It is appropriate for applications needing isolation capabilities and protection against backflow currents during power-down states. Consider the specific operating temperature range and the need for 3.6-V I/O tolerance if interfacing with higher voltage logic levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus family, which focuses on high-density bus transceivers. The SN74AUC16245 series is part of the AUC logic family, characterized by ultra-low power consumption and high speed. It serves as a bridge for data movement in complex digital systems where voltage levels and power efficiency are critical constraints.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives within the same Widebus family or other AUC series variants. Verify that any substitute maintains the required 0.8-V to 2.7-V operating range and similar propagation delay specifications.
