SN74LVCH16245ADGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH16245ADGVR is a 16-bit (dual-octal) noninverting bus transceiver designed for asynchronous communication between data buses. It operates from a supply voltage of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation in 5-V input/output environments with 3.3-V VCC. The device provides a maximum propagation delay of 4 ns at 3.3 V and includes active bus-hold circuitry on data inputs to maintain valid logic states without external resistors. It utilizes a TVSOP-48 package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-48 package configuration required for your design. Confirm RoHS compliance status and lead finish details via the manufacturer's current orderable addendum. Ensure the component meets the moisture sensitivity level ratings specified for surface-mount assembly processes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring bidirectional data transfer between buses operating at different voltage levels. It is suitable for applications needing down-voltage translation from 5-V sources to lower voltage domains. Consider the 16-bit width and dual-octal structure for high-density data routing requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments Widebus Family of logic devices. It is functionally similar to other members like the SN74LVC16245A but offers specific LVCH characteristics. The device can be configured as two independent 8-bit transceivers or a single 16-bit transceiver depending on control pin usage.
