Description and Introduction

3.3-V ABT QUADRUPLE BUS BUFFERS WITH 3-STATE OUTPUTS **Manufacturer:** Texas Instruments (TI)  

**Part Number:** SN74LVTH125DBRG4  

**Specifications:**  
- **Technology Family:** LVTH (Low-Voltage BiCMOS Technology with TTL-Compatible Inputs)  
- **Supply Voltage Range:** 2.7V to 3.6V  
- **Number of Channels:** 4  
- **Output Type:** 3-State  
- **High-Level Output Current:** -32mA  
- **Low-Level Output Current:** 64mA  
- **Propagation Delay Time:** 3.7ns (max) at 3.3V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SSOP-14  

**Descriptions:**  
The SN74LVTH125DBRG4 is a quad bus buffer gate with 3-state outputs. It is designed for low-voltage (2.7V to 3.6V) operation while maintaining TTL-compatible input levels. The device features independent output-enable (OE) inputs for each buffer, allowing for flexible bus management.  

**Features:**  
- Supports mixed-mode signal operation (5V input and output voltages with 3.3V VCC)  
- Inputs accept voltages up to 5.5V  
- Bus-hold on data inputs eliminates the need for external pull-up/pull-down resistors  
- Ioff supports partial-power-down mode operation  
- Latch-up performance exceeds 500mA per JESD 78  
- ESD protection exceeds 2000V per JESD 22 (Human Body Model)

Application Scenarios & Design Considerations

3.3-V ABT QUADRUPLE BUS BUFFERS WITH 3-STATE OUTPUTS

Alternative Part Number

  • 74LVTH125PW,118 --: Same LVT-family quad bus buffer with 3-state outputs, different manufacturer and package naming, direct functional replacement.
  • MC74LVX125DTR2G --: Quad 3-state buffer in TSSOP with comparable 3.3V low-voltage logic characteristics, different series prefix for easy distinction.
  • SN74LVC125APWR --: TI quad 3-state buffer in TSSOP with similar drive and voltage range, different logic family (LVC) so clearly distinguishable from the source.
  • MC74LVX125DTG --: Quad 3-state buffer in TSSOP with similar low-voltage CMOS characteristics, suitable drop-in functional replacement.
  • 74LVC125APW,118 --: Quad 3-state buffer in TSSOP with comparable drive and pinout; LVC family offers similar performance for most applications.
