SN74AVCH4T245PWR

The SN74AVCH4T245PWR is a 4-bit dual-supply Bus Transceiver with configurable voltage translation and 3-state outputs. It uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2 to 3.6V. It is optimized to operate with VCCA/VCCB set at 1.4 to 3.6V. It is operational with VCCA/VCCB as low as 1.2V. It is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input and the OE\ input activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated.

• Fully configurable dual-rail design
• I/Os are 4.6V tolerant
• Ioff Supports partial power-down-mode operation
• Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
• Latch-up performance exceeds 100mA per JESD 78, Class II
• Green product and no Sb/Br
