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 500MHz
• LVTTL-compatible control Inputs
• Undershoot Clamp Diodes on all switch and control Inputs
• Low I/O capacitance, 4pF typical
• Available in QSOP and TSSOP packages
APPLICATIONS:
• Hot-swapping
• 10/100 Base-T, Ethernet LAN switch
• Low distortion analog switch

DESCRIPTION:
The QS3VH384 HotSwitch is a high bandwidth, 10-bit bus switch. The
QS3VH384 has very low ON resistance, resulting in under 250ps propagation
delay through the switch. Two banks of five switches are controlled by
independent(xOE),LVTTLcompatiblesignals forbidirectionaldataflowwith
noaddeddelayorgroundbounce. IntheONstate,theswitchcanpasssignals
up to 5V. In the OFF state, the switches offer very high impedence at the
terminals.
The combination of near-zero propagation delay, high OFF impedance, and
over-voltage tolerance makes the QS3VH384 ideal for high performance
communicationsapplications.
The QS3VH384 is characterized for operation from -40°C to +85°C.
