The CBTLV3384 is a ten bit high-speed bus switch with low on-state resistance of the switch allowing connections to be made with minimal propagation delay. The device is organized as dual 5-bit bus switches with separate output-enable (OE) inputs, to allow use as two 5-bit bus switches or one 10-bit bus switch. When OE is low, the associated 5-bit bus switch is on and A port is connected to B port. When OE is high, the switch is open, and a high- impedance state exists between the two ports. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The IDT 74CBTLV3384 is a low‑voltage, 10‑bit bi‑directional bus switch designed for high‑speed bus switching and isolation. It features dual 5‑bit switches that can be used as two separate 5‑bit switches or combined into a single 10‑bit switch, with over‑voltage tolerant propagation delay and latch‑up performance exceeding 100 mA.
