PI3B3245 3.3V, Hot Insertion, 8-Bit, 2-Port NanoSwitchTM Power Supply Characteristics Parameters Description Test Conditions(1) Min Typ (2) Max Units ICC Quiescent Power Supply Current VCC = Max. VIN = GND or VCC 0.1 3.0 μA ΔICC Supply Current per Input HIGH VCC = Max. VIN = 3.0V(3) 750 μA Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device. 2. Typical values are at VCC = 3.3V, +25°C ambient. 3. Per TTL driven input (control input only); A and B pins do not contribute to ICC. Switching Characteristics over Operating Range Parameters Description Test Conditions Com. Units Min Max tPLH tPHL Propagation Delay(1,2) Ax to Bx, Bx to Ax CL = 50 pF RL = 500Ω 0.25 ns tPZH tPZL Bus Enable Time BE to Ax or Bx 1.0 4.0 tPHZ tPLZ Bus Disable Time BE to Ax or Bx 1.0 4.5 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 ca- pacitance. The time constant for the switch alone is of the order of 0.25 ns for 50 pF 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, AN may be driven low to 0V and high to 3.6V. Driving BN 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. 10-0247 |
