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. 1 www.diodes.com April 2018 Diodes Incorporated A product Line of Diodes Incorporated PI3B3257 Maximum Ratings (Above which the useful life may be impaired.

Min. to Yn(1,2) tIY Propagation Delay In tSY Bus Select Time, Sn to Yn tPZH tPZL Bus Enable Time, E to Yn tPHZ tPLZ Bus Disable Time, E to Yn Units Max. 0.25 CL = 50pF RL = 500Ω 1 4.5 1 4.5 1 4.8 ns Notes: 1. This parameter is guaranteed but not tested on Propagation Delays. 2. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The switch’s time constant alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. Applications Information Logic Inputs The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a + 3.3V supply, IN may be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail® minimizes power consumption. Power-Supply Sequencing and Hot-Plug Information Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC and GND before applying signals to input/ output or control pins. Rail-to-Rail is a registeredtrademark of Nippon Motorola, Ltd.
