### Descriptions:  
The SN74LVC138ADR is a high-performance, low-voltage CMOS 3-to-8 line decoder/demultiplexer. It is designed for 1.65V to 3.6V VCC operation and features three enable inputs (two active low and one active high) to simplify cascading and reduce system power consumption.  

### Features:  
- **Wide Operating Voltage Range**: 1.65V to 3.6V  
- **Low Power Consumption**: ICC = 10 µA (max)  
- **High Noise Immunity**: CMOS technology  
- **Schmitt-Trigger Inputs**: Allows slow input transition  
- **ESD Protection**: Exceeds 2000V per JESD 22  
- **Latch-Up Performance**: Exceeds 250 mA per JESD 17  
- **Three Enable Inputs**: Simplifies cascading  
- **Output Drive Capability**: Supports 24 mA output current  
- **Small Package**: SOIC-16 for space-constrained applications  

This device is suitable for memory address decoding, data routing, and other digital logic applications.
