PI3G612 1.8/3.3V High-Bandwidth 6-channel, 2:1 Mux/DeMux with switched Pull-ups Description Features The PI3G612 is a 3-port, 6-channel, 1:2 multiplexer/demultiplexer. It features switched 100 K-Ohm active pull-ups on output ports A and B to prevent disconnected floating signals and thereby reduce system noise and power. The Y port can be connected to either the A or B ports, or alternatively both ports can be isolated, disconnected, or all connected. When the EP pin is low, the pull-up transistors are off. When EP is high, the pull-up transistors are on. If EP is not connected, an internal pull-down will turn the pull-up off. If pullups are not used, EP should be connected to ground. The PI3G612 has a wide operating voltage range, very low power consumption and small packaging suitable for mobile, and handheld equipment. • Near-Zero propagation delay • • • • • • • • • 5Ω switches connect inputs to outputs Signal passing bandwidth, 400 MHz Rail-to-Rail™ switching 1.8V to 3.3V supply voltage operation Supports live insertion and hot-swap Industrial operating temperature: -40ºC to +85ºC 2KV ESD HBM Latch-up performance >250mA per JESD17 Packaging: 28-contact TQFN (3.5 x 5.0, 0.5mm pad pitch) Block Diagram Applications EP • Memory card switching SA SB • Photo printers • Mobile devices CONTROL DECODER Y0 A0 B0 Pin Configuration (Top-side view) B0 25 A0 28 27 26 EP VDD Y1 B1 24 A1 23 B1 3 22 GND Y2 4 21 A2 VDD 5 20 B2 Y3 6 19 VDD GND 7 18 A3 Y4 8 17 B3 Y5 9 16 A4 SB 10 15 B4 GND GND 11 12 13 14-0062 14 Y2 A2 B2 Y3 A3 B3 Y4 A4 B4 Y5 A5 2 VDD Y1 B5 1 SA Y0 A1 A5 B5 1 www.pericom.com04/29/14 PI3G612 1.8/3.3V High-Bandwidth 6-channel, 2:1 Mux/DeMux with switched Pull-ups Pin Description Pin Name Description AX, BX, YX Data I/O SA, SB Channel Select Inputs EP Pull-ups Enable GND Ground VDD Power Truth Table Control Inputs EP SB 0 0 0 0 0 1 0 1 1 0 1 1 1 0 1 1 SA 0 1 0 1 0 Switch State1 Bx Open Open Closed Closed Open 1 0 1 Open Closed Closed Pullup State Function2 Ax Open Closed Open Closed Open Off Off Off Off On Closed Open Closed On On On Y, A, B all disconnected and Hi-Z Y=A, B =Hi-Z Y=B, A =Hi-Z Y=A=B Y, A, B all disconnected; Y=Hi-Z; A & B pull to VDD Y=A; A & B pull toVDD Y=B; A& B pull to VDD Y=A=B; A& B pull to VDD Notes: 1.

Typical values are at nominal VDD, TA = 25°C ambient and maximum loading. 3. Measured by the voltage drop between Y and In pin at indicated current through the switch. On-Resistance is determined by the lower of the voltages on the two (Y, In) pins. 4.

See test circuit and waveforms. 2. This parameter is guaranteed but not tested on Propagation Delays. 3. The switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.30ns for 10pF 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 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. 14-0062 4 www.pericom.com04/29/14 PI3G612 1.8/3.3V High-Bandwidth 6-channel, 2:1 Mux/DeMux with switched Pull-ups Test Circuit for Electrical Characteristics(1-5) 2 x VDD VDD 200-ohm VIN Pulse Generator VOUT D.U.T 10pF CL RT 200-ohm Notes: 1.
