FEATURES:
IDTQS3VH16233
DESCRIPTION:
• 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
Ω typical
• Low RON - 4Ω
• 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
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.

NOTES:
1. See Test Conditions under TEST CIRCUITS AND WAVEFORMS.
2. This parameter is guaranteed but not production tested.
3. The bus switch contributes no propagation 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 0.2ns at CL = 50pF. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the
system. Propagation delay of the bus 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.
4. Minimums are guaranteed but not production tested.
5. Maximum toggle frequency for Sx control input (pass voltage > VCC, VIN = 5V, RLOAD > 1MΩ, no CLOAD).
