Description and Introduction

Octal Buffer/Driver With 3-State Outputs The SN74LVCH244A is an octal buffer/line driver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Technology 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 Options:** SOIC, TSSOP, TVSOP  

### **Descriptions:**  
- The SN74LVCH244A is an octal buffer/line driver with 3-state outputs.  
- It is designed for 1.65V to 3.6V VCC operation but can tolerate 5.5V on inputs and outputs when powered down.  
- The device features two active-low output enables (OE) for independent control of the four buffers each.  

### **Features:**  
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **Partial Power-Down Protection (Ioff):** Allows outputs to be disabled when VCC is 0V.  
- **Supports Mixed-Mode Signal Operation:** 5V inputs and outputs when VCC is 3.3V.  
- **ESD Protection:** Exceeds 2000V (HBM) and 1000V (CDM).  
- **Low Power Consumption:** ICC typically 10µA.  

This information is sourced from the official Texas Instruments datasheet for the SN74LVCH244A.

Application Scenarios & Design Considerations

Octal Buffer/Driver With 3-State Outputs

Alternative Part Number

  • 74LVC244A --: Same octal buffer/line driver function with 3.3V LVC-family logic levels; Nexperia's 74LVC244A is a widely available pin-compatible alternative, though it lacks the bus-hold feature of the LVCH variant.
  • MC74LCX244A --: Octal buffer/line driver in the LCX low-voltage CMOS family with 5V-tolerant inputs, functionally equivalent to the SN74LVCH244A for most level-shifting and buffering applications.
  • 74LVTH244A --: LVTH family includes bus-hold on inputs, closely matching the 'H' bus-hold characteristic of the SN74LVCH244A, making it a strong functional drop-in for bus-holding buffer applications.
