FSTU3125 Datasheet (Fairchild Semiconductor) - 4-Bit Bus Switch with −2V Undershoot Protection

FSTU3125, 4-Bit Bus Switch with −2V Undershoot Protection

The Fairchild Switch FSTU3125 provides four high-speed CMOS TTL-compatible bus switches.

The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.

The A and B Ports are protected against undershoot to s
