低逻辑电平
Logic Level - Low | The TC7MB3245FK provides eight bits of high-speed TTL-compatible bus switching in a standard ’245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as one 8-bit switch. When output enable ( OE ) is low, the switch is on and port A is connected to port B. When OE is high, the switch is open and a high-impedance state exists between the two ports. All inputs are equipped with protection circuits against static discharge. Operating voltage: VCC = 4.5~5.5 V High speed: tpd = 0.25 ns (max) Low on resistance: RON = 5 Ω (typ.) ESD performance: Human body model > ±2000 V Machine model > ±200 V Compatible with TTL outputs (control inputs) Package: VSSOP (US20) Pin compatible with the 74xx245 type. Functionally equivalent to (FST/CBT) 3245. |
高逻辑电平
Logic Level - High | TC7MB3245FK在一个标准的'245器件的引脚配置提供8位高速TTL兼容总线开关。低通态电阻的开关允许以最小的传播延迟连接。该设备被组织为一个8位的开关。当输出使能（OE）为低，开关打开和端口A连接到端口B。当OE高，开关打开和高阻抗状态之间存在着两个端口。所有输入都配有保护电路防止静电放电。 工作电压：VCC= 4.5〜5.5 V 高速：TPD =0.25 ns（最大） 低导通电阻RON= 5Ω（典型值） ESD性能：人体模式>±2000 V 机模型>±200 V 兼容TTL输出（控制输入） 包装：VSSOP（US20） 与74xx245类型引脚兼容。 其功能相当于（FST/ CBT）3245。 |
