### **Descriptions:**
The SN74LVCH245ADBR is an octal bus transceiver designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and is compatible with mixed-mode signal operation. It supports bidirectional data flow controlled by the direction (DIR) input and has an output-enable (OE) input to disable the outputs.
### **Features:**
- **Wide Operating Voltage Range:** 1.65V to 3.6V
- **Supports Mixed-Mode Voltage Operation**
- **Bus-Hold on Data Inputs (Eliminates Need for External Pull-up/Pull-down Resistors)**
- **Ioff Supports Partial-Power-Down Mode Operation**
- **ESD Protection Exceeds 2000V per JESD 22**
- **Latch-Up Performance Exceeds 250mA per JESD 78**
- **3-State Outputs for Bus Isolation**
- **Bidirectional Data Flow Control (DIR Pin)**
