SN74AVC16T245ZQLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC16T245ZQLR is a 16-bit dual-supply bus transceiver with configurable voltage translation and tri-state outputs. It operates with VCCA and VCCB ranging from 1.2V to 3.6V, supporting universal bidirectional translation between 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V nodes. The device features overvoltage-tolerant I/Os up to 4.6V, VCC isolation for high-impedance states when power is lost, and Ioff support for partial-power-down modes. It is housed in a 56-pin BGA Microstar Junior package.

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 disables outputs to prevent damaging current backflow during partial-power-down conditions.
• VCC isolation feature forces both ports into a high-impedance state if either supply input is at ground potential.
• Overvoltage-tolerant inputs and outputs enable mixed-voltage-mode data communications without external protection.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ZQLR corresponds to the 56-pin BGA Microstar Junior package configuration. Confirm RoHS compliance status and check for any product change notifications or end-of-life notices associated with this specific ordering variant before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for asynchronous communication between data buses requiring noninverting level shifting. Ensure the application utilizes separate configurable power rails for Port A and Port B within the 1.2V to 3.6V range. Verify that the DIR and OE control signals are referenced correctly to VCCA for proper direction and enable functionality.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AVC16T245 family of 16-bit dual-supply bus transceivers. It shares core functional specifications with other package variants such as TSSOP and TVSOP versions, differing primarily in physical footprint and thermal characteristics while maintaining identical electrical performance and logic operations.
