SN74CBT16211CDGVR

24位FET总线开关5 -V总线， 2 -V冲保护开关 24-BIT FET BUS SWITCH 5-V BUS SWITCH WITH 2-V UNDERSHOOT PROTECTION

description/ordering information

The SN74CBT16211C 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 SN74CBT16211C provides protection for undershoot up to −2 V by sensing an undershoot event and ensuring that the switch remains in the proper OFF state.
