SN74LVC16245ADLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16245ADLR is a 16-bit bus transceiver with 3-state outputs from the Texas Instruments Widebus family. It operates on a supply voltage range of 1.65 V to 3.6 V and features inputs tolerant up to 5.5 V, supporting mixed-mode signal operation. The device provides a maximum propagation delay of 4 ns at 3.3 V and includes Ioff circuitry for partial-power-down mode. It is housed in a 48-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports asynchronous communication between data buses using two independent direction-control (DIR) inputs.
• Features Ioff circuitry that disables outputs to prevent damaging current backflow during power-down.
• Inputs accept voltages up to 5.5 V regardless of the VCC level, enabling down-voltage translation.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DLR' corresponds to the SSOP-48 package and tape-and-reel carrier configuration. Confirm RoHS compliance status and lead finish details via the manufacturer's latest orderable addendum. Ensure design compatibility with the specified operating temperature range and thermal resistance metrics for the selected package type.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit bidirectional interface is required within the 1.65-V to 3.6-V logic domain. The 5.5-V input tolerance allows direct interfacing with legacy 5-V systems without additional level shifting. Consider the 4-ns propagation delay and output drive capabilities for high-speed data bus applications requiring low skew.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC16245A series, designed as a member of the Texas Instruments Widebus family. It functions as either one 16-bit or two 8-bit non-inverting transceivers. The ADLR variant specifically denotes the SSOP package form factor intended for surface-mount assembly.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function?

The Ioff circuitry automatically disables the outputs when the device is powered down, preventing damaging current backflow through the device into the disabled power rail.

Can this device translate signals from 5-V to 3.3-V systems?

Yes, the inputs are overvoltage tolerant up to 5.5 V at any valid VCC, allowing it to be used as a translator in mixed 3.3-V/5-V system environments.
