Description and Introduction

3.3-V 20-Bit Bus-Interface Flip-Flop with 3-State Outputs The SN74ALVCH16821DGGR is a 20-bit bus-interface flip-flop with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits:** 20  
- **Output Type:** 3-State  
- **Voltage Supply Range:** 1.65V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** TSSOP-56  
- **Mounting Type:** Surface Mount  
- **High-Level Output Current:** -24mA  
- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time:** 2.7ns (max) at 3.3V  
- **Input Capacitance:** 3.5pF (typical)  

### **Descriptions and Features:**  
- Designed for 1.65V to 3.6V VCC operation.  
- Supports mixed-mode signal operation (5V input/output with 3.3V VCC).  
- Bus-hold on data inputs eliminates the need for external pull-up/pull-down resistors.  
- 3-state outputs for bus-oriented applications.  
- Flow-through pinout for optimized PCB layout.  
- Latch-up performance exceeds 250mA per JESD 17.  
- ESD protection exceeds JESD 22 (2000V HBM, 200V MM).  
- Supports partial power-down mode operation.  

This device is commonly used in high-performance digital systems requiring wide data bus interfacing.
