Description and Introduction

3.3-V ABT Octal Buffers/Drivers With 3-State Outputs 20-TSSOP -40 to 85 The SN74LVTH244APWRG4 is a 3.3-V ABT octal buffer/driver with 3-state outputs, manufactured by Texas Instruments (TI).  

### **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  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Type:** TSSOP-20  
- **Number of Channels:** 8 (Octal)  
- **Output Type:** 3-State  
- **Propagation Delay Time:** 3.5 ns (max) at 3.3 V  
- **I/O Type:** Non-Inverting  

### **Descriptions:**  
The SN74LVTH244APWRG4 is designed for bus interface applications requiring high drive and fast switching performance. It features 3-state outputs that allow multiple devices to share a common bus without interference.  

### **Features:**  
- **Supports Mixed-Mode Voltage Operation** (5-V Input and Output Voltages with 3.3-V Supply)  
- **Bus-Hold on Data Inputs** (Eliminates Need for External Pull-Up/Pull-Down Resistors)  
- **High Output Drive** (±12 mA at 3.3 V)  
- **ESD Protection** (Exceeds 2000 V per JESD 22)  
- **Latch-Up Performance** (Exceeds 500 mA per JESD 78)  
- **Available in TSSOP-20 Package**  

This device is commonly used in communication systems, networking equipment, and other digital applications requiring buffering and signal driving.

Application Scenarios & Design Considerations

3.3-V ABT Octal Buffers/Drivers With 3-State Outputs 20-TSSOP -40 to 85

Alternative Part Number

  • 74LVTH244APW,118 --: Same LVTH octal buffer/line driver function in TSSOP-20 package, direct functional equivalent from a different manufacturer and naming series.
  • MC74LVX244DTR2G --: Octal buffer/line driver with 3-state outputs in TSSOP-20, similar low-voltage CMOS logic family and pin-compatible footprint.
  • 74LVC244APW,118 --: Widely available octal buffer/line driver in TSSOP-20 with 3-state outputs; LVC family offers comparable low-voltage performance though with lower bus-drive rating than LVTH.
  • 74LVTH244APW --: Same LVTH244A octal buffer function in TSSOP package, pin-compatible and widely available from an alternate source.
  • MC74LVX244ADTR2G --: Octal buffer/line driver with similar low-voltage CMOS characteristics in TSSOP, suitable functional replacement.
  • 74LVC244APW --: Octal buffer in TSSOP with comparable drive and pinout; check supply voltage and drive current requirements before use.
