Texas Instruments SN74CBTLV3257 Low-Voltage 4-Bit 1-Of-2 FET Multiplexer/Demultiplexer 74CBTLV3257RGYRG4

The SN74CBTLV3257 is a low-voltage 4-bit 1-of-2 FET multiplexer/demultiplexer designed for high-speed applications. It features a low on-state resistance of 5 Oc, enabling efficient connections with minimal propagation delay. The device supports rail-to-rail switching on data I/O ports and includes an I_off feature that allows for partial-power-down mode operation, preventing backflow of damaging current when powered down. The output-enable (OE) input disables the multiplexers/demultiplexers when set high, ensuring isolation during power-off conditions. This component is suitable for various applications, including Internet of Things (IoT) devices, wireless headphones, and television sets. It is available in multiple package types, including VQFN, with a temperature range of -40 to 85 degrees Celsius.
