Description

The 74CBTLV3126DBQRG4 is a signal switch that operates as a single 20-bit bus switch or as a dual 10-bit bus switch. It provides high-speed switching with very low ON resistance, resulting in under 250ps propagation delay through the switch. When the Output Enable (OE) is low, the corresponding 10-bit bus switch is on and port A is connected to Port B. When OE is high, the switch is off and a high impedance exists between Port A and Port B. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor.
