SN74AUC16245DGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC16245DGVR is a 16-bit (dual-octal) noninverting bus transceiver from the AUC logic family, housed in a 48-pin TVSOP package. It operates within a supply voltage range of 0.8 V to 2.7 V and supports mixed-mode signal operation with 3.6-V I/O tolerance. The device features a maximum propagation delay of 2 ns at 1.8 V and provides ±8-mA output drive current. It includes dedicated Ioff circuitry for partial-power-down mode and meets high ESD protection standards.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-48 package configuration. Confirm that the required operating temperature range aligns with the -40°C to +85°C specification. Ensure design compatibility with the 0.8-V to 2.7-V supply voltage limits and check that input transition rates do not exceed the specified slew rate requirements for reliable switching performance.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low-voltage operation below 1.8 V with fast switching speeds. It is suitable for applications needing bidirectional data transfer with independent direction control for each octal section. Consider the 3.6-V I/O tolerance if interfacing with higher voltage peripherals. Verify that the thermal characteristics of the TVSOP package meet the system's heat dissipation requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to Texas Instruments' Widebus family, optimized for 1.8-V operation. It serves as a high-performance alternative to standard logic families by offering lower power consumption and faster propagation delays. The dual-octal architecture allows flexible configuration as either two 8-bit or one 16-bit transceiver.
