UCA9306 CMOS IC
DUAL BIDIRECTIONAL I2C BUS AND SMBUS VOLTAGE-LEVEL TRANSLATOR
DESCRIPTION
The UTC UCA9306 device is a dual bidirectional I2C and SMBus voltage-level translator with an enable(EN) input, and is operational from 1.2-V to 3.3-V VREF1 and 1.8-V to 5.5-V VREF2.
The UTC UCA9306 device allows bidirectional voltage translations between 1.2V and 5V,without the use of a direction pin .The low ON-state resistance (RON) of the switch allows connections to be made with minimal propagation delay. When EN is high, the translator switch is ON , and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, respectively, allowing bidirectional data flow between ports. When EN is low, the translator switch is off, and a high-impedance state exists between ports.
In addition to voltage translation, the UTC UCA9306 device can be used to isolate a 400-kHz bus from a 100-kHz busby controlling the EN pin, and disconnecting the slower bus during fast-mode communication.

UCA9306 CMOS 集成電路
雙向 I2C 線和 SMBus 電壓電平轉換器
描述
UTC UCA9306 是一款雙向 I2C 和 SMBus 電壓電平轉換器,具備使能(EN)輸入,工作範圍為 1.2V 至 3.3V 的 VREF1 和 1.8V 至 5.5V 的 VREF2。
UTC UCA9306 支援 1.2V 至 5V 之間的雙向電壓轉換,無需使用方向控制引腳。開關的低導通電阻(RON)可實現最小的傳播延遲。當 EN 為高電平時,轉換器開關導通,SCL1 和 SDA1 I/O 分別連接至 SCL2 和 SDA2 I/O,實現雙向數據流。當 EN 為低電平時,轉換器開關關閉,兩端處於高阻抗狀態。
除了電壓轉換,UTC UCA9306 還可用於通過控制 EN 引腳將 400-kHz 線路與 100-kHz 線路隔離,從而在快速模式通信時斷開較慢的線路。
特點
- 適用於混合模式 I2C 應用的 SDA 和 SCL 線路的雙位雙向轉換器
- 與 I2C 和 SMBus 相容
- 最大傳播延遲小於 1.5ns,適用於標準模式和快速模式 I2C 裝置及多主機
- 支援以下電壓電平轉換:
- 1.2V VREF1 與 1.8V、2.5V、3.3V 或 5V VREF2
- 1.8V VREF1 與 2.5V、3.3V 或 5V VREF2
- 2.5V VREF1 與 3.3V 或 5V VREF2
- 3.3V VREF1 與 5V VREF2
- 提供無方向引腳的雙向電壓轉換
- 低 3.5-Ω 導通電阻,減少信號失真
- 開漏 I2C I/O 引腳(SCL1、SDA1、SCL2 和 SDA2)
- 支援混合模式信號操作的 5V 耐受性 I2C I/O 引腳
- 當 EN 為低電平時,SCL1、SDA1、SCL2 和 SDA2 引腳處於高阻抗狀態
- 無鎖定操作,實現 EN 為低電平時的隔離
- 流通式引腳設計,便於印刷電路板佈線
