- **Supply Voltage Range:** **1.65V to 3.6V**  
- **Input Voltage Range:** **0V to 5.5V** (tolerant)  
- **Output Drive Capability:** **±24mA** at 3.3V  
- **Propagation Delay:** **4.5ns (max) at 3.3V**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package Type:** **TSSOP-16**  
- **Number of Inputs:** **3 (A0, A1, A2)**  
- **Number of Outputs:** **8 (Y0-Y7, active LOW)**  
- **Enable Inputs:** **Three (E1, E2, E3)** for flexible control  

### **Description:**
The **IDT74LVC138AQ** is a high-performance, low-voltage decoder/demultiplexer designed for **1.65V to 3.6V** operation. It decodes **three binary address inputs (A0-A2)** into **eight mutually exclusive outputs (Y0-Y7, active LOW)**. The device features **three enable inputs (E1, E2, E3)**, allowing for cascading and system-level control.  

### **Features:**
- **Wide Operating Voltage Range (1.65V–3.6V)**  
- **5V-Tolerant Inputs** (allows interfacing with 5V logic)  
- **High-Speed Operation** (4.5ns max propagation delay)  
- **Low Power Consumption** (optimized for battery-operated devices)  
- **Schmitt Trigger Inputs** for improved noise immunity  
- **ESD Protection** (exceeds 2000V per JESD22-A114)  
- **Pb-Free & RoHS Compliant**  

This device is commonly used in **address decoding, memory selection, and data routing** applications.
