- **I/O Type:** 3-State  

### **Descriptions:**
- The SN74LVCH245APWRG4 is an octal bus transceiver designed for asynchronous communication between data buses.  
- It features non-inverting 3-state outputs and operates at low voltage (1.65V to 3.6V).  
- The direction of data flow is controlled by the DIR (Direction) input, while the OE (Output Enable) pin enables/disables the outputs.  
- It supports partial power-down protection using Ioff circuitry.  

### **Features:**
- **Wide Operating Voltage:** 1.65V to 3.6V  
- **5V-Tolerant Inputs/Outputs** (allows interfacing with 5V logic)  
- **Bus-Hold on Data Inputs** (eliminates need for external pull-up/pull-down resistors)  
- **Supports Mixed-Mode Signal Operation** (allows 3.3V/2.5V/1.8V interfacing)  
- **Low Power Consumption:** ICC = 10μA (max)  
- **ESD Protection:** >2000V (HBM)  
- **3-State Outputs** for bus-oriented applications  
- **High Drive Outputs** (±24mA at 3.3V)

### **Descriptions:**
- The SN74LVCH245APWRG4 is an octal bus transceiver designed for asynchronous communication between data buses.
- It operates at 3.3V and supports bidirectional data flow with 3-state outputs.
- The device includes bus-hold circuitry to prevent floating inputs and over-voltage tolerant inputs for interfacing with higher-voltage systems.

### **Features:**
- **3.3V Operation:** Optimized for 2.7V to 3.6V VCC operation.
- **Bus-Hold Circuitry:** Eliminates the need for external pull-up/pull-down resistors.
- **Over-Voltage Tolerant Inputs:** Allows interfacing with 5V signals.
- **Power-Off Protection:** Inputs and outputs are high impedance when VCC is 0V.
- **3-State Outputs:** Supports bus-oriented applications.
- **Low Power Consumption:** Designed for energy-efficient operation.
