Description and Introduction

3.3-V ABT Octal Buffers/Drivers With 3-State Outputs The SN74LVTH240PW is a 3.3-V ABT octal buffer/driver with 3-state outputs, manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Technology:** 3.3-V LVTTL (Low-Voltage TTL)  
- **Logic Type:** Inverting Buffer/Driver  
- **Number of Channels:** 8 (Octal)  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 2.7 V to 3.6 V  
- **High-Level Output Current:** -32 mA  
- **Low-Level Output Current:** 64 mA  
- **Propagation Delay Time:** 3.1 ns (Max) at 3.3 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP (PW)  

### **Descriptions:**  
The SN74LVTH240PW is designed for bus-oriented applications and features inverting outputs with 3-state control. It is optimized for low-voltage (3.3 V) operation while maintaining TTL input/output compatibility.  

### **Features:**  
- Supports mixed-mode signal operation (5-V input and output voltages with 3.3-V VCC)  
- Bus-hold on data inputs eliminates the need for external pull-up/pull-down resistors  
- Ioff feature supports partial-power-down mode  
- Latch-up performance exceeds 500 mA per JESD 78  
- ESD protection exceeds 2000 V per MIL-STD-883, Method 3015  

This device is commonly used in digital systems requiring buffering, signal inversion, or bus driving.

Description and Introduction

3.3-V ABT Octal Buffers/Drivers With 3-State Outputs The SN74LVTH240PW is a 3.3-V ABT octal buffer/driver with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Technology Family:** LVTH (Low-Voltage BiCMOS Technology)  
- **Supply Voltage Range:** 2.7 V to 3.6 V  
- **Input Voltage Range:** 0 V to 5.5 V  
- **Output Drive Capability:** ±12 mA at 3.3 V  
- **Propagation Delay:** 3.7 ns (max) at 3.3 V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Type:** TSSOP (PW)  
- **Pin Count:** 20  

### **Description:**  
The SN74LVTH240PW is an octal buffer/driver designed for 3.3-V VCC operation. It features 3-state outputs that can be placed in a high-impedance state, allowing multiple devices to share a common bus. The device supports mixed-voltage applications with 5-V tolerant inputs.  

### **Features:**  
- **3-State Outputs** for bus-oriented applications  
- **5-V Tolerant Inputs** allow interfacing with 5-V logic  
- **Supports Partial Power-Down Mode** (Ioff circuitry disables outputs when VCC = 0 V)  
- **Bus-Hold Data Inputs** eliminate the need for external pull-up/pull-down resistors  
- **Latch-Up Performance Exceeds 500 mA per JESD 78**  
- **ESD Protection Exceeds JESD 22** (2000-V Human-Body Model, 200-V Machine Model)
