Details

Offering seamless communication between different voltage nodes, the SN74AVCH8T245DGVR is a reliable 8-bit noninverting bus transceiver with configurable power-supply rails for A and B ports. Supporting bidirectional translation between 1.2V to 3.6V voltage levels, this device ensures universal low-voltage compatibility. The asynchronous data transfer capability allows for smooth communication between data buses, with the option to disable outputs using the OE input. The active bus-hold circuitry maintains unused inputs at a valid logic state, eliminating the need for additional resistors. With Ioff protection for partial-power-down applications and VCC isolation for added safety, this transceiver solution is ideal for single-supply systems and offers easy replacement with minimal PCB redesign for future upgrades
