SN74LVC16245ADLRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16245ADLRG4 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. The maximum propagation delay is 4 ns at 3.3 V, with typical output ground bounce of 2 V at VCC = 3.3 V. It supports mixed-mode signal operation on all asynchronous communication ports. The device includes Ioff circuitry for partial-power-down mode and back-drive protection. ESD protection exceeds JESD 22 standards, rated at 2000 V Human-Body Model and 1000 V Charged-Device Model.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type matches the design requirements, as the SN74LVC16245A series is available in TSSOP, TVSOP, and SSOP configurations. Confirm that the ordering suffix corresponds to the desired tape and reel quantity and lead finish. Ensure the selected variant meets the required operating temperature range and RoHS compliance status for the target assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between buses requiring asymmetric voltage translation or mixed-signal environments. The wide supply voltage range accommodates low-power applications down to 1.65 V. Consider the 5.5 V tolerant inputs for direct connection to legacy 5-V logic without additional level shifting components. Evaluate the drive strength and parasitic capacitance against the load requirements to ensure signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus family, designed for efficient asynchronous data transfer across multiple channels. It functions as either two independent 8-bit transceivers or a single 16-bit transceiver. The architecture minimizes external timing constraints while providing robust isolation capabilities through dedicated output-enable controls.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function during power-down?

The Ioff circuitry automatically disables the outputs when VCC is 0 V, preventing damaging current backflow through the device into powered buses.

What is the maximum input voltage tolerance?

The inputs accept voltages up to 5.5 V regardless of the VCC supply level, enabling safe operation in mixed 3.3-V and 5-V system environments.
