SN74CBTLV3245AZQNR

The SN74CBTLV3245AZQNR from Texas Instruments is an octal FET bus switch providing eight bits of high-speed bus switching. It features a standard '245 device pinout and low on-state resistance for minimal propagation delay. The device is organized as one 8-bit switch, connecting port A to port B when the output enable (OE) is low.

Key electrical characteristics include a bandwidth of 200 MHz, an on-state resistance of 5 Ohms (typical), and a maximum on-state resistance of 40 Ohms. It supports a supply voltage range of 2.3V to 3.6V and can handle input/output voltages up to 3.6V. The switch offers robust ESD protection, exceeding 2000V for the Human-Body Model.

This bus switch is available in a 20-BGA MICROSTAR JUNIOR package (4x3) with surface mount mounting type. It operates within a temperature range of -40°C to 85°C. The device also supports partial power-down mode operation with its Ioff feature, ensuring no damaging current backflows when powered down, and provides isolation during power off.

Applications for the SN74CBTLV3245AZQNR include general-purpose bus switching, signal routing, and systems requiring low-voltage operation and high-speed data transfer. Its design ensures reliable performance in various electronic systems.
