Key Features

SN74LVC8T245RHLR is an 8-bit dual-supply bus transceiver from Texas Instruments, designed to facilitate bidirectional data transfer between different voltage levels. It supports input and output voltages ranging from 1.65 V to 5.5 V, allowing seamless interfacing between devices operating at various logic levels. The device features a fully configurable dual-rail design, enabling each port to operate over the full power-supply range. Control inputs, including Output Enable (OE) and Direction Control (DIR), provide flexibility in managing data flow and bus isolation. The VCC isolation feature ensures that if either VCC input is at ground, all outputs are in the high-impedance state, preventing unwanted current flow. Additionally, the device exhibits latch-up performance exceeding 100 mA per JESD 78, Class II, enhancing its reliability in demanding applications. Encased in a compact 24-pin VQFN package measuring 5.5 mm × 3.5 mm, it is suitable for space-constrained designs.

Applications

Voltage-level translation in mixed-voltage systems.
Bidirectional data buses in computing and networking equipment.
Portable electronics requiring efficient power management.
Industrial automation systems with multiple logic level requirements.
Communication devices interfacing with different voltage standards.
