### **Descriptions:**  
- The SN74LS14DBR is a hex inverter with Schmitt-trigger inputs, designed to improve noise immunity and signal conditioning.  
- It operates within standard TTL logic levels and is commonly used in noise-sensitive applications.  

### **Features:**  
- **Schmitt-Trigger Inputs:** Provides hysteresis for improved noise rejection.  
- **Standard TTL Compatibility:** Works with 5V logic systems.  
- **High Noise Immunity:** Reduces false triggering.  
- **Wide Operating Voltage Range:** Supports 4.75V to 5.25V.  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Surface-Mount Package (SSOP-14):** Compact for space-constrained designs.  

This information is based solely on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Hex schmitt-trigger inverters

Alternative Part Number

  • MC74LS14DR2G --: Hex Schmitt-trigger inverter in the same LS logic family with equivalent pinout and function, available in SOIC package.
  • 74LS14D --: Direct functional equivalent hex Schmitt-trigger inverter in SOIC-14, widely available and pin-compatible.
  • SN74HC14DR --: Same hex Schmitt-trigger inverter function in SOIC-14 from the same vendor, using HC CMOS technology for lower power though with different speed characteristics.
  • DM74LS14MX --: Classic 74LS14 hex Schmitt-trigger inverter from a different series prefix, same logic function and SOIC-14 package, widely used as a substitute.
