IDTQS34XVH2245

2.5V / 3.3V 32-BIT HIGH

BANDWIDTH BUS SWITCH

FEATURES:

DESCRIPTION:

• N channel FET switches with no parasitic diode to VCC

– Isolation under power-off conditions

– No DC path to VCC or GND

The QS34XVH2245 is a high bandwidth, 32-bit bus switch. The

QS34XVH2245 with 25Ω resistance and 1.35ns propagation delay is

ideal for line matching and low noise environments. The switches can

be turned ON under the control of individual LVTTL-compatible Output

Enable (OEx) signals for bidirectional data flow with no added delay or

ground bounce. In the ON state, the switches can pass signals up to 5V.

In the OFF state, the switches offer very high impedance at the

terminals.

– 5V tolerant in OFF and ON state

• 5V tolerant I/Os

• 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

• LVTTL-compatible control Inputs

• Undershoot Clamp Diodes on all switch and control Inputs

• Low I/O capacitance, 4pF typical

• 25Ω resistors for low noise and line matching

• Available in 80-pin QVSOP package

The combination of small propagation delay, high OFF impedance,

and over-voltage tolerance makes the QS34XVH2245 ideal for high

performance communications applications.

The QS34XVH2245 is characterized for operation from -40°C to

+85°C.

APPLICATIONS:

• Hot-swapping

• Low distortion analog switch

• Replaces mechanical relay

• ATM 25/155 switching
