SN74LVC16245AZRDR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16245AZRDR 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 Ioff circuitry for partial-power-down mode support. It offers ESD protection exceeding 2000 V via the human-body model and latch-up performance exceeding 250 mA per JESD 78 standards.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type associated with the suffix 'ZRDR' against the official TI orderable addendum, as standard documentation lists DGG, DGV, and DL packages. Confirm that the requested variant matches the active production status and lead finish specifications found in the latest packaging information. Ensure compatibility with required moisture sensitivity levels and peak reflow temperatures for the manufacturing process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring bidirectional data transfer between buses with different voltage domains. It is suitable for applications needing high drive capability and fast switching speeds within low-voltage environments. Consider the 5.5 V tolerant inputs for interfacing with legacy 5-V logic without additional level shifting components.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial-power-down scenarios?

The integrated Ioff circuitry automatically disables the outputs when VCC is 0 V, preventing damaging back-drive currents through the device.

What is the maximum input voltage tolerance?

Inputs accept voltages up to 5.5 V regardless of the VCC supply level, allowing safe operation in mixed 3.3-V and 5-V systems.
