Description and Introduction

Octal Buffer/Driver With 3-State Outputs The SN74ALVCH244DW is a 3.3-V octal buffer/driver with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 1.65 V to 3.6 V  
- **High-Speed Operation:** 2.5 ns max at 3.3 V  
- **Output Drive Capability:** ±24 mA at 3.0 V  
- **Low Power Consumption:** ICC = 10 µA (max)  
- **Input/Output Tolerance:** Supports 5-V inputs when VCC = 3.3 V  
- **Bus-Hold Data Inputs:** Eliminates the need for external pull-up/pull-down resistors  
- **Latch-Up Performance:** Exceeds 250 mA per JESD 17  
- **ESD Protection:**  
  - 2000-V Human-Body Model (A114-A)  
  - 1000-V Charged-Device Model (C101)  

### **Descriptions:**  
The SN74ALVCH244DW is designed for 1.65-V to 3.6-V VCC operation and is part of TI's ALVCH family. It features eight non-inverting buffers with 3-state outputs, allowing bidirectional data flow. The device is ideal for driving high-capacitance loads and low-impedance backplanes.  

### **Features:**  
- **3-State Outputs:** Allows multiple devices to share a common bus  
- **Bus-Hold on Data Inputs:** Maintains last valid logic state when inputs are floating  
- **Partial Power-Down Protection (Ioff):** Supports live insertion  
- **Package Type:** SOIC (DW) – 20-pin  

This device is commonly used in memory interfaces, networking equipment, and other digital systems requiring high-speed buffering.
