SN74CBT16210C中文资料具有 –2V 下冲保护和 2 个控制输入的 5V、1:1 (SPST)、20 通道 FET 总线开关数据手册TI规格书

描述 Description

The SN74CBT16210C 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 SN74CBT16210C 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 SN74CBT16210C is organized as two 10-bit bus switches with separate output-enable (1OE\\, 2OE\\) inputs. It can be used as two 10-bit bus switches or as one 20-bit bus switch. When OE\\ is low, the associated 10-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 10-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.
