A product Line of Pb Diodes Incorporated Lead-free Green PI3B3245 TM 3.3V, Hot Insertion, 8-Bit, 2-Port NanoSwitch Features Description Near-Zero propagation delay e PTh I3B3245 is a 3.3V 8-bit, 2-port bus switch designed with a low On-Resistance (5-ohm) allowing inputs to be connected di- 5-ohm switches connect inputs to outputs rectly to outputs. e bTh us switch creates no additional propaga - Fast Switching Speed: 4.5ns (max.) tional delay or additional ground bounce noise. The switches are Ultra-Low Quiescent Power (0.2A Typical) turned ON by the Bus Enable (BE) input signal. Ideally suited for notebook applications TTL-compatible control of inputs levels Block Diagram ESD protection (2kV Human Body Model and 200V Machine Model) Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) A0 SW B0 Halogen and Antimony Free. Green Device (Note 3) For automotive applications requiring specic cfi hange control A7 SW B7 (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative.

GND pin must be connected to supply ground for proper device operation. For enhanced thermal, electrical, and board level performance, the exposed pad needs to be soldered to the board using a corresponding thermal pad on the board and for proper heat conduction through the board, thermal vias need to be incorporated in the PCB in the thermal pad region. www.diodes.com December 2019 PI3B3245 2 Diodes Incorporated Document Number DS40710 Rev 2-2
