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.
The VS3V125 is designed for 3.3V to 2.5V, or 2.5V to 1.8V level translation, without any external
components. 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.
