General Description

The VS3V125 contains a set of four high-speed, low-resistance bus switches. Each bus switch is individually controlled by LVTTL-compatible, active-low control input (/xOE). The low ON resistance of VS3V125 allows inputs to be connected to outputs without adding propagation delay and without generating additional signal noise.

Features

• Enhanced N-FET with no dc path to VCC or

GND in normal operating signal voltage range.

• Low impedance bidirectional data flow

• Pin-compatible with CBTLV3215 switch

• Zero added ground bounce or signal noise

• LVTTL-compatible control signals

• Undershoot clamp diodes on all

switch and control pins

• ESD rating >2000V (Human Body

Model) or >200V (Machine Model)

• Latch-up current >100mA

• Available in 150-mil wide QSOP

package
