N.C. GND PI3V312 Low On-Resistance, 3.3V High-Bandwidth 4-Port, 2:1 Mux/DeMux VideoSwitch Features Description Near-Zero propagation delay Pericom Semiconductors PI3V312 is a 4-port, 2:1 Multiplexer/ Demultiplexer with 3-state outputs. The switch introduces no ad- 5 switches connect inputs to outputs ditional ground bounce noise or propagation delay. High signal passing bandwidth (500MHz) Low On-Resistance and High bandwidth make it ideal for video Beyond Rail-to-Rail switching and other applications. Also this device has exceptionally low 5V I/O tolerant with 3.3V supply crosstalk and off-isolation, which is far greater than most analog 2.5V and 3.3V supply voltage operation switches offered today. A single 3.3V supply is all that is required for operation. Hot insertion capable The PI3V312 offers a high-performance (500MHz), low-cost solu- Industrial operating temperature: -40C to +85C tion to switch between video signals that have high bandwidth. 2KV ESD Protection (human body model) Latch-up performance >250mA per JESD17 Packaging (Pb-free & Green available): 16-pin QSOP (Q) 16-pin TSSOP (L) 20-contact TQFN (ZH) Block Diagram Pin Configuration A B B C C A I 1 I 0 I 1 I 0 I 1 D D I 0 I 0 I 1 1 20 2 19 N.C. 1 16 S V S CC 15 A 2 EN 3 18 I 0 EN A I 0 14 EN A 3 D I 1 I 0 17 4 D I 0 IA 1 4 13 D Y I 1 A 16-pin 5 16 20-Contact D Y I 1 A L, Q 12 B 5 Y ZH I 0 D 6 15 Y D B I 0 6 11 B C I 1 I 0 S 7 14 C B I 0 I 1 7 10 C Y I 1 B 8 13 C I 1 Y B GND 8 9 Y C 12 9 Y N.C.
