Texas Instruments SN74CBT3125 Quadruple FET Bus Switch Datasheet
The SN74CBT3125 is a quadruple FET bus switch featuring independent line switches. Each switch connects two ports when the output-enable (OE) input is low and disconnects them when high. The device supports TTL-compatible input levels and operates over an industrial temperature range of -40°C to 85°C.
