SN74LVCH16245ADLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH16245ADLR is a 16-bit bus transceiver with 3-state outputs from the Texas Instruments Widebus family. It operates from 1.65 V to 3.6 V and features inputs accepting voltages 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 active bus-hold circuitry on data inputs. It supports Ioff for live insertion and partial-power-down modes. The component is housed in a 48-pin SSOP package.

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 against 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 for applications requiring bidirectional level translation between 1.65-V and 5.5-V domains. The device is suitable for systems needing high drive capability with low quiescent current. Consider the 48-pin SSOP footprint for space-constrained designs requiring 16-bit width. Verify that input transition rates remain within specified limits to ensure timing accuracy.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCH16245A series, designed as a member of the Texas Instruments Widebus family. It functions as a dual-octal or single 16-bit noninverting bus transceiver. The device integrates direction control and output enable inputs to manage data flow between A and B ports efficiently.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused data inputs?

Active bus-hold circuitry holds unused or undriven data inputs at a valid logic state, eliminating the need for external pullup or pulldown resistors.

What is the function of the Ioff feature?

The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device and supporting live insertion.
