产品概述
The SN74CBT3125C is a high-speed TTL-compatible FET bus switch with low ON-state resistance (ron), allowing for minimal propagation delay. Active Undershoot-Protection Circuitry on the A and B ports of the SN74CBT3125C provides protection for undershoot up to –2 V by sensing an undershoot event and ensuring that the switch remains in the proper OFF state.The SN74CBT3125C is organized as four 1-bit bus switches with separate output-enable (1OE\, 2OE\, 3OE\, 4OE\) inputs. It can be used as four 1-bit bus switches or as one 4-bit bus switch. When OE\ is low, the associated 1-bit bus switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports. When OE\ is high, the associated 1-bit bus switch is OFF, and the high-impedance state exists between the A and B ports.This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that damaging current will not backflow through the device when it is powered down.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.
