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.
