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
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
multiplexersorasone32-bitto16-bitmultiplexer. SELxinputscontrolthe
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.

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
Thecombinationofnear-zeropropagationdelay, highOFFimpedance,
and over-voltage tolerance also makes the QS3VH16233 ideal for high
performancecommunicationsapplications.
The QS3VH16233 is characterized for operation from -40°C to +85°C.
• 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
