SN74CBTLV3251DBQR Description

Short technical summary and product information.

The SN74CBTLV3251DBQR from Texas Instruments is a versatile 1-of-8 high-speed FET multiplexer/demultiplexer. This device features low on-state resistance, allowing for minimal propagation delay in signal paths. It supports rail-to-rail switching on data I/O ports and is fully specified for partial-power-down applications using its Ioff feature, which prevents damaging current backflow when the device is powered down.

 

The select inputs (S0, S1, S2) control the data flow, while the output enable (OE) input, when high, disables the multiplexer/demultiplexer, ensuring a high-impedance state during power transitions. The SN74CBTLV3251DBQR is housed in a 16-SSOP package and operates across a temperature range of -40°C to 85°C, making it suitable for various industrial and commercial applications.

 

Key features include a 5 Ohm switch connection between ports, support for partial-power-down mode, and latch-up performance exceeding 100mA per JESD 78, Class II. The device is designed for applications requiring efficient signal routing and isolation.
