SN74LVC16245AGRDR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16245AGRDR is a 16-bit bus transceiver from the Texas Instruments Widebus family, designed for asynchronous communication between data buses. It operates within a supply voltage range 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 a 3.3-V VCC. The device provides three-state outputs and supports bidirectional data transmission controlled by direction (DIR) and output-enable (OE) pins. It includes Ioff circuitry for partial-power-down mode and back-drive protection. The component is housed in a 48-pin GRD package.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function?

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

What is the maximum input voltage tolerance?

Inputs accept voltages up to 5.5 V regardless of the VCC supply voltage, enabling use in mixed 3.3-V/5-V systems.
