TC7MB3245FK B245 的参数

类型 Type 总线开关 Bus Switch
电路 Circuit
独立电路 Independent Circuits
输出高,低电流 Current - Output High, Low
单电源 Voltage Supply Source 单电源 Single Supply
电源电压 Voltage - Supply 4.5 V ~ 5.5 V
Description & Applications 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 ? (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.
描述与应用 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。
