SN74AVC16T245GQLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC16T245GQLR is a 16-bit dual-supply bus transceiver with configurable level-shifting and tri-state outputs. It utilizes two separate power rails, VCCA and VCCB, supporting voltages from 1.2V to 3.6V. The device enables universal bidirectional translation between low-voltage nodes including 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. It features overvoltage-tolerant I/Os rated at 4.6V, partial-power-down support via Ioff, and VCC isolation for high-impedance states when supplies are grounded.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-rail design allows independent operation of ports across the full 1.2V to 3.6V supply range
• Ioff circuitry supports partial-power-down mode by disabling outputs to prevent backflow current
• VCC isolation feature ensures both ports enter a high-impedance state if either supply input is at ground potential

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the GQL suffix corresponds to the 56-pin BGA Microstar Junior package (7x4.5mm) before procurement. Confirm RoHS compliance status as specified in the latest datasheet revision. Ensure ESD handling protocols meet JESD 22 standards during assembly. Validate that the specific manufacturing lot aligns with current production data sheets.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for asynchronous communication between data buses requiring mixed-voltage interfacing. The device is suitable where control inputs must reference VCCA. Consider thermal impedance characteristics for the BGA package in dense layouts. Ensure unused inputs are tied to logic levels to prevent excessive leakage currents.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVC16T245 family of 16-bit dual-supply bus transceivers. The GQL suffix specifically denotes the 56-pin BGA Microstar Junior package variant. Other variants include TSSOP and TVSOP packages with different pin counts and thermal profiles within the same functional family.
