IDTQS3VH16233 INDUSTRIAL TEMPERATURE RANGE 2.5V / 3.3V 32:16 MUX/DEMUX HIGH BANDWIDTH BUS SWITCH QUICKSWITCH PRODUCTS IDTQS3VH16233 2.5V / 3.3V 32:16 MUX/DEMUX HIGH BANDWIDTH BUS SWITCH FEATURES: DESCRIPTION: N channel FET switches with no parasitic diode to Vcc The QS3VH16233 HotSwitch is a 32-bit to 16-bit high bandwidth bus Isolation under power-off conditions switch, which can multiplex or demultiplex data. The QS3VH16233 has No DC path to Vcc or GND very low ON resistance, resulting in under 250ps propagation delay 5V tolerant in OFF and ON state through the switch. This device can be used as two 16-bit to 8-bit 5V tolerant I/Os multiplexers or as one 32-bit to 16-bit multiplexer. SELx inputs control the Low RON - 4 typical data flow. TESTx inputs control either one or two ports connection. In the Flat RON characteristics over operating range OFF and ON states, the switches are 5V-tolerant. In the OFF state, the Rail-to-rail switching 0 - 5V switches offer very high impedance at the terminals. Bidirectional dataflow with near-zero delay: no added ground The combination of near-zero propagation delay, high OFF impedance, bounce and over-voltage tolerance also makes the QS3VH16233 ideal for high Excellent RON matching between channels performance communications applications. Vcc operation: 2.3V to 3.6V The QS3VH16233 is characterized for operation from -40C to +85C. High bandwidth - up to 500 MHz LVTTL-compatible control Inputs Undershoot Clamp Diodes on all switch and control Inputs Low I/O capacitance, 4pF typical Available in TSSOP package APPLICATIONS: Hot-swapping 10/100 Base-T, Ethernet LAN switch Low distortion analog switch Replaces mechanical relay ATM 25/155 switching FUNCTIONAL BLOCK DIAGRAM TEST1 TEST2 SEL1 SEL2 x = 1 through 8 x = 9 through 16 xB2 xB2 xA xA xB1 xB1 ONE OF EIGHT CHANNELS ONE OF EIGHT CHANNELS The IDT logo is a registered trademark of Integrated Device Technology, Inc.
