VS3125
VS3125 is Quad Bus Switch with Individual Active Low Enables manufactured by Vaishali Semiconductor.
Description
The VS3125 contains a set of four high-speed, low-resistance bus switches. Each bus switch is individually controlled by TTL-patible, active-low control input (/x OE). 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 patible 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.
