| Description & Applications |
The TC7WPB9306 and TC7WPB9307 are CMOS 2-bit dual-supply bus switches that can provide an interface between two nodes at different voltage levels. These devices can be connected to two independent power supplies. VCCA supports 1.8-V, 2.5-V and 3.3-V power supplies, whereas VCCB supports 2.5-V, 3.3-V and 5.0V power supplies. Bidirectional level-shifting is possible by simply adding external pull-up resistors between the An/Bn data lines and the VCCA / VCCB supplies. There is no restriction on the relative magnitude of the An and Bn voltages; both the An and Bn data lines can be pulled up to arbitrary power supplies. The enable signal can be used to disable the device so that the buses are effectively isolated. The Output Enable ( OE :TC7WPB9307, OE:TC7WPB9306) input is common for all the two-bits of the data lines; thus these device are used as a single two-bits bus switch. For the TC7WPB9306, Output Enable (OE) is active-High: When OE is High, the switch is on; when Low, the switch is off. For the TC7WPB9307, Output Enable ( OE ) is active-Low: When OE is Low, the switch is on; when High, the switch is off. The TC7WPB9306 and TC7WP9307 supports power-down protection at the OE ,OE input, with OE ,OE being 5.5-V tolerant. The channels consist of n-type MOSFETs. All the inputs provide protection against electrostatic discharge. Operating voltage:1.8-V to 2.5-V, 1.8-V to 3.3-V, 1.8-V to 5.0-V, 2.5-V to 3.3-V, 2.5-V to 5.0-V or 3.3-V to 5.0-V bidirectional interface Operating voltage: VCCA = 1.65 to 5.0 V, VCCB = 2.3 to 5.5 V Low ON-resistance: RON = 5.0 Ω (typ.) (ON-resistance test circuit: VIS = 0 V, IIS = 30 mA, VCCA= 3.0 V , VCCB = 4.5 V) ESD performance: Machine model ≥ ±200 V Human body model ≥ ±2000 V 5.5-V tolerance and power-down protection at the Output Enable input.

| 描述与应用 |
TC7WPB9306和TC7WPB9307是CMOS 2位双电源总线开关，可以在不同的电压水平，在两个节点之间提供一个接口。这些设备可以连接到2独立的电源。 VCCA支持1.8 V，2.5 V和3.3 V电源，而VCCB支持2.5 V，3.3 V和5.0V电源。可以通过简单地增加 An/Bn 数据线 和 VCCA/VCCB 供应之间的外部上拉电阻实现双向电平转换。An和Bn的电压的相对大小没有限制,AN和Bn数据线可以被拉升到任意电源。使能信号可用于禁用设备使总线有效隔离。对所有二位的数据线来说，输出使能输入（OE：TC7WPB9307 OE编号：TC7WPB9306）是共同的，因此，这些设备被用作一个单一的双位总线开关。对于TC7WPB9306，输出使能是高有效。当OE为高，开关是开着的，当低，开关处于关闭状态。对于TC7WPB9307，低有效：当OE是低电平时，开关是开着的，高时，开关处于关闭状态。该通道是由n型的MOSFET组成的。所有的输入提供保护，防止静电放电。 工作电压:1.8-V至2.5 V，1.8 V到3.3 V，1.8 V到5.0 V，2.5 V至3.3 V，2.5 V到5.0 V或3.3 V到5.0 V 双向接口 工作电压：VCCA=1.65至5.0 V，VCCB=2.3?5.5 V 低导通电阻：RON=5.0Ω（典型值） （导通电阻测试电路：VIS =0 V，IIS= 30mA，VCCA= 3.0 V，VCCB=4.5 V） ESD性能：机器型号≥±200 V 人体模式≥±2000 V 5.5-V宽容和掉电保护功能的输出使能输入。 软件包：CST8 US8 |
