SN74CBT3306CDR

具有 –2V 下冲保护的 5V、1:1 SPST、2 通道 FET 总线开关（低电平有效） 8-SOIC -40 to 85

description/ordering information

The SN74CBT3306C 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 SN74CBT3306C provides protection for undershoot up to −2 V by sensing an  undershoot event and ensuring that the switch remains in the proper OFF state.

● Undershoot Protection for Off-Isolation on A and B Ports Up To −2 V

● Bidirectional Data Flow, With Near-Zero Propagation Delay

● Low ON-State Resistance ron Characteristics ron = 3 Ω Typical

● Low Input/Output Capacitance Minimizes Loading and Signal Distortion CioOFF = 5 pF Typical

● Data and Control Inputs Provide Undershoot Clamp Diodes

● Low Power Consumption ICC = 3 µA Max
