Description and Introduction

18-Bit Universal Bus Transceiver With 3-State Outputs The SN74ALVCH16501 is a 18-bit universal bus transceiver manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Logic Type:** Universal Bus Transceiver  
- **Number of Bits:** 18  
- **Voltage Supply Range:** 1.65V to 3.6V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Input/Output Type:** 3-State  
- **Propagation Delay:** Typically 2.5 ns at 3.3V  
- **Output Drive Capability:** ±24 mA at 3V  
- **Package Options:** TSSOP (56-pin), TVSOP (56-pin)  

### **Descriptions:**
- Designed for asynchronous communication between data buses.  
- Supports bidirectional data flow with independent control inputs for direction.  
- Features 3-state outputs for bus-oriented applications.  
- Optimized for low-voltage (1.65V to 3.6V) and high-speed operation.  

### **Features:**
- **Wide Operating Voltage:** Supports 1.65V to 3.6V for mixed-voltage systems.  
- **Bus-Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **Partial Power-Down Protection:** Allows inputs to be powered down without affecting outputs.  
- **ESD Protection:** Exceeds 2000V (HBM) and 1000V (CDM).  
- **Flow-Through Pinout:** Simplifies PCB layout.  

This device is commonly used in networking, computing, and communication systems requiring high-speed, low-voltage data transfer.
