Description and Introduction

3.3-V 20-Bit Flip-Flop With 3-State Outputs The SN74ALVCH162721 is a 20-bit universal bus driver manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Logic Type:** Universal Bus Driver  
- **Number of Bits:** 20  
- **Supply Voltage Range:** 1.65V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** 3-State  
- **Package Options:** 56-pin TSSOP, 56-pin TVSOP  

### **Descriptions and Features:**  
- Designed for low-voltage (1.65V to 3.6V) applications.  
- Supports mixed-mode signal operation (5V input and output voltages with 3.3V supply).  
- Features flow-through pinout for optimized PCB layout.  
- Provides high-drive outputs (±24 mA at 3V).  
- Includes bus-hold data inputs to eliminate the need for external pull-up/pull-down resistors.  
- Supports partial power-down mode (Ioff circuitry disables outputs when VCC = 0V).  
- Latch-up performance exceeds 250 mA per JESD 17.  
- ESD protection exceeds 2000V (HBM) and 200V (MM).  

For more detailed electrical characteristics and timing diagrams, refer to the official TI datasheet.
