TEXAS INSTRUMENTS SN74CB3Q3244PW 逻辑芯片, 总线开关, FET, 8位, 20TSSOP
description/ordering information
The SN74CB3Q3244 is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage of the pass transistor, providing a low and flat ON-state resistance ron. The low and flat ON-state resistance allows for minimal propagation delay and supports rail-to-rail switching on the data input/output I/O ports.
High-Bandwidth Data Path Up To 500 MHz†
5-V-Tolerant I/Os with Device Powered Up or Powered Down
