QUICKSWITCH® PRODUCTS 2.5V / 3.3V 32:16 MUX/DEMUX HIGH BANDWIDTH BUS SWITCH
IDTQS3VH16233
FEATURES:
• N channel FET switches with no parasitic diode to Vcc − Isolation under power-off conditions − No DC path to Vcc or GND − 5V tolerant in OFF and ON state
• 5V tolerant I/Os • Low RON - 4Ω typical • Flat RON characteristics over operating range • Rail-to-rail switching 0 - 5V • Bidirectional dataflow with near-zero delay: no added ground
bounce • Excellent RON matching between channels • Vcc operation: 2.3V to 3.6V • 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
DESCRIPTION:
The QS3VH16233 HotSwitch is a 32-bit to 16-bit high bandwidth bus switch, which can multiplex or demultiplex data. The QS3VH16233 has very low ON resistance, resulting in under 250ps propagation delay through the switch. This device can be used as two 16-bit to 8-bit multiplexers or as one 32-bit to 16-bit multiplexer. SELx inputs control the data flow. TESTx inputs control either one or two ports connection. In the OFF and ON states, the switches are 5V-tolerant. In the OFF state, the switches offer very high impedance at the terminals.
The combination of near-zero propagation delay, high OFF impedance, and over-voltage tolerance also makes the QS3VH16233 ideal for high performance communications applications.
The QS3VH16233 is characterized for operation from -40°C to +85°C.
