SN74CBT3306CPWRG4
数字总线开关 IC Dual FETBus Switch
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
