SN74CB3T3306中文资料具有电平转换器的 3.3V、1:1 (SPST)、2 通道 FET 总线开关数据手册TI规格书

描述 Description

The SN74CB3T3306 device is a high-speed TTL-compatible FET bus switch with low ON-state resistance (ron), allowing for minimal propagation delay. The device fully supports mixed-mode signal operation on all data I/O ports by providing voltage translation that tracks VCC. The SN74CB3T3306 device supports systems using 5-V TTL, 3.3-V LVTTL, and 2.5-V CMOS switching standards, as well as user-defined switching levels.
