DUAL BUS TRANSCEIVER The TC7WH245FU is a bidirectional voltage level translator manufactured by TOSHIBA. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:
### **Specifications:**
- **Type:** Bidirectional Voltage Level Translator
- **Supply Voltage Range (VCCA):** 1.65V to 3.6V
- **Supply Voltage Range (VCCB):** 2.3V to 5.5V
- **Operating Temperature Range:** -40°C to +85°C
- **Number of Channels:** 8
- **Logic Family:** CMOS
- **Package:** TSSOP20
- **Direction Control:** Yes (DIR pin)
- **High-Speed Operation:** tpd = 4.3 ns (max) at 3.3V ↔ 5.0V translation
- **Low Power Consumption:** ICC = 10 μA (max)
- **I/O Ports:** 3-state, non-inverting
### **Descriptions:**
- The TC7WH245FU is an 8-bit bidirectional level shifter that allows voltage translation between two different voltage domains (e.g., 1.8V ↔ 3.3V or 3.3V ↔ 5V).
- It features a direction control (DIR) pin to determine data flow (A→B or B→A).
- Designed for mixed-voltage systems in applications such as I²C, SPI, and general-purpose logic interfacing.
### **Features:**
- **Bidirectional Voltage Translation:** Supports translation between two voltage levels without external components.
- **Automatic Direction Sensing:** Controlled via the DIR pin.
- **Wide Voltage Range:** Supports VCCA (1.65V–3.6V) and VCCB (2.3V–5.5V).
- **High-Speed Operation:** Suitable for fast data transmission.
- **Low Power Consumption:** Ideal for battery-powered devices.
- **3-State Outputs:** Allows bus isolation when OE (Output Enable) is inactive.
- **ESD Protection:** HBM 2000V (min).
