Description and Introduction

3-TO-8 LINE DECODER The TC74LVX138FT is a low-voltage CMOS 3-to-8 line decoder/demultiplexer manufactured by Toshiba. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage Range (VCC):** 2.0V to 5.5V  
- **High-Speed Operation:** tpd = 5.9ns (max) at 5V  
- **Low Power Consumption:** ICC = 4μA (max) at 5V  
- **Input Levels:**  
  - TTL-compatible (5V tolerant)  
  - CMOS-compatible  
- **Output Drive Capability:** ±12mA at 3.0V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-16  

### **Description:**  
The TC74LVX138FT is a high-performance, low-voltage decoder/demultiplexer designed for 2V to 5.5V operation. It decodes three binary address inputs (A0, A1, A2) into one of eight mutually exclusive outputs (Y0-Y7). It features three enable inputs (E1, E2, E3) for cascading and control flexibility.  

### **Features:**  
- **3-to-8 Line Decoding:** Converts 3-bit binary input to one active-low output.  
- **Demultiplexing Capability:** Can function as a 1-to-8 demultiplexer with E3 as the data input.  
- **Multiple Enable Inputs:** E1 and E2 (active low) and E3 (active high) for easy expansion.  
- **Power-Down Protection:** Inputs include diodes for protection against voltage spikes.  
- **TTL and CMOS Compatibility:** Supports mixed-voltage system interfacing.  
- **Low Noise:** Designed with controlled output slew rates.

Application Scenarios & Design Considerations

3-TO-8 LINE DECODER

Alternative Part Number

  • SN74LV138APWR --: Same 3-to-8 line decoder/demultiplexer function in the LV logic family, widely available and pin-compatible in TSSOP package.
  • MC74LVX138DTR2G --: Direct LVX-family 3-to-8 decoder equivalent with matching function and TSSOP package, good second source.
  • 74LV138PW --: Low-voltage 3-to-8 decoder in TSSOP, functionally equivalent and a common alternative from a different series naming.
  • SN74LV138APW --: Same 3-to-8 line decoder/demultiplexer function in the LV logic family, TSSOP package, widely available and pin-compatible in function.
  • MC74LVX138DT --: LVX-family 3-to-8 decoder with matching logic thresholds and TSSOP package, offering similar speed and drive characteristics.
