Description and Introduction

16-Bit Buffer/Driver With 3-State Outputs The SN74LVCH162244ADGGR is a 16-bit buffer/driver manufactured by Texas Instruments. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Type:** Buffer/Driver  
- **Number of Bits:** 16  
- **Logic Family:** LVCH (Low-Voltage CMOS with TTL-compatible inputs)  
- **Supply Voltage Range:** 1.65V to 3.6V  
- **Input Voltage Range:** 0V to 5.5V  
- **Output Drive Capability:** ±24mA at 3.3V  
- **Propagation Delay:** 3.7ns (max) at 3.3V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-48  
- **Output Type:** 3-State  

### **Descriptions:**  
The SN74LVCH162244ADGGR is a 16-bit buffer/driver designed for 1.65V to 3.6V VCC operation. It features non-inverting outputs with 3-state control, allowing multiple outputs to be connected to a shared bus. The device is optimized for low-voltage, high-speed operation while maintaining TTL-compatible input levels.

### **Features:**  
- Supports mixed-mode signal operation (5V input and output voltages with 3.3V VCC)  
- Bus-hold on data inputs eliminates the need for external pull-up/pull-down resistors  
- Ioff feature supports partial-power-down mode operation  
- Latch-up performance exceeds 250mA per JESD 17  
- ESD protection exceeds 2000V per JESD 22  

This information is strictly factual and derived from the manufacturer's datasheet.

Application Scenarios & Design Considerations

16-Bit Buffer/Driver With 3-State Outputs

Alternative Part Number

  • 74LVC162244APAG --: Same 16-bit buffer/driver function with 3.3V LVC-family logic and 5V-tolerant inputs, available in TSSOP package; functionally equivalent to the LVCH162244A.
  • 74LVC16244ADGG --: 16-bit non-inverting buffer/driver in the LVC family with similar drive strength and TSSOP-48 footprint; a widely available cross-family substitute when bus-hold is not strictly required.
  • 74LVT16244BDGG --: 16-bit buffer/driver in the LVT family offering comparable 3.3V operation, 5V-tolerant inputs and bus-hold behavior, making it a close functional replacement for the LVCH162244A.
  • MC74LCX16244ADTG --: 16-bit non-inverting buffer with 5V tolerant inputs and similar propagation delay, offered in 48-pin TSSOP; a common second-source for LVCH16244-type parts.
