VS3125
Quad Bus Switch with
Individual Active Low Enables
Applications
•= 5v to 3.3V translation in mixed supply environment
•= Hot Swap interface
•= Video, audio switching
•= Clock gating
•= Logic replacement
General Description
The VS3125 contains a set of four high-speed, low-resistance bus switches. Each bus switch is individually
controlled by TTL-compatible, active-low control input (/xOE). The low ON resistance of VS3125 allows
inputs to be connected to outputs without adding propagation delay and without generating additional signal
noise.
The VS3125 is function and pinout compatible with QS3125. It enables 5V to 3.3V level translation when
used with an external diode in the power supply line. In addition, the high off-isolation between switch
terminals in the ‘disable’ mode, and the near-zero propagation delay in the ‘on’ state make the VS3V125 an
ideal interface element for hot-swapping applications.
