Description and Introduction

Octal Buffer/Driver With 3-State Outputs The SN74LVC2244APW is a 20-bit buffer/driver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Technology Family:** LVC  
- **Supply Voltage Range:** 1.65V to 3.6V  
- **Input Voltage Range:** 0V to 5.5V  
- **Output Drive Capability:** ±24mA at 3.3V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Type:** TSSOP (PW)  
- **Number of Channels:** 20  
- **Propagation Delay Time:** 3.8ns (max) at 3.3V  
- **I/O Type:** 3-State  

### **Descriptions:**  
- The SN74LVC2244APW is a 20-bit non-inverting buffer/driver designed for 1.65V to 3.6V VCC operation.  
- It features 3-state outputs that can be placed in a high-impedance state to avoid bus contention.  
- The device is suitable for voltage translation between different logic levels.  

### **Features:**  
- Supports mixed-mode voltage operation (5V input with 3.3V VCC)  
- Low power consumption (ICC = 10µA max)  
- Ioff supports partial-power-down mode  
- ESD protection exceeds 2000V per JESD 22  
- Latch-up performance exceeds 250mA per JESD 17  

This information is based on TI's official datasheet for the SN74LVC2244APW.

Application Scenarios & Design Considerations

Octal Buffer/Driver With 3-State Outputs

Alternative Part Number

  • 74LVC2244APW --: Same octal buffer/line driver function with 3.3V LVC family and 5V tolerant inputs, pin-compatible in TSSOP package.
  • MC74LCX244ADTR2G --: LCX family octal buffer with similar 3.3V operation and 5V tolerant inputs, functionally equivalent in TSSOP.
  • 74LVC244APW --: Standard LVC octal buffer without the series damping resistors; widely available drop-in functional substitute when series resistors are not critical.
