Description and Introduction

OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS The SN74LVCR2245ADB is a 8-bit bus transceiver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Logic Type:** Bus Transceiver  
- **Number of Bits:** 8  
- **Voltage - Supply:** 2.3V to 3.6V  
- **Operating Temperature:** -40°C to +85°C  
- **Output Type:** 3-State  
- **Package / Case:** SSOP-20  
- **Mounting Type:** Surface Mount  
- **High-Level Output Current:** -24mA  
- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time:** 4.3ns (max) at 3.3V  
- **Independent Circuits:** 1  

### **Descriptions:**
- The SN74LVCR2245ADB is an octal bus transceiver designed for 2.3V to 3.6V VCC operation.  
- It features non-inverting 3-state outputs and is designed for asynchronous communication between data buses.  
- The direction control (DIR) input determines data flow (A to B or B to A).  
- The output-enable (OE) input disables the outputs when high.  

### **Features:**
- **Supports Mixed-Mode Voltage Operation** (5V tolerant inputs when powered at 3.3V)  
- **Bus-Hold on Data Inputs** (Eliminates need for external pull-up/pull-down resistors)  
- **Partial Power-Down Protection** (Ioff circuitry disables outputs when VCC is 0V)  
- **ESD Protection** (Exceeds 2000V per JESD 22)  
- **Low Power Consumption** (ICC typically 10µA)  
- **3-State Outputs**  

This device is commonly used in data communication systems, networking equipment, and other digital logic applications requiring bidirectional voltage-level translation.
