Description and Introduction

16 x 4 asynchronous FIFO memory The SN74ALS232BDW is a dual retriggerable monostable multivibrator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology Family:** ALS  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** SOIC (DW)  
- **Number of Channels:** 2  
- **Output Type:** Push-Pull  
- **Propagation Delay Time:** Typically 12 ns  
- **Input Type:** Schmitt Trigger  

### **Descriptions:**  
The SN74ALS232BDW features two independent retriggerable monostable multivibrators with Schmitt-trigger inputs for noise immunity. It is designed for precision timing applications, allowing pulse width extension upon retriggering.  

### **Features:**  
- **Retriggerable Operation:** Allows pulse width extension by retriggering before the output pulse ends.  
- **Schmitt-Trigger Inputs:** Provides improved noise immunity.  
- **Wide Operating Voltage Range:** Supports 4.5V to 5.5V operation.  
- **High-Speed Operation:** Low propagation delay for timing-critical applications.  
- **Push-Pull Outputs:** Provides strong drive capability.  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

16 x 4 asynchronous FIFO memory

Alternative Part Number

  • 74ALS232BD --: Same 74ALS232 function (dual 4-bit FIFO register) in the same SOIC-16 wide package, offered by an alternate vendor for drop-in replacement.
  • SN74ALS232BN --: Identical ALS232 FIFO register function from TI in a PDIP-16 package, suitable when through-hole mounting is acceptable.
  • 74ALS232BDW --: Equivalent ALS232 dual 4-bit FIFO register in SOIC-16 wide body from a second source, matching the original package and logic family.
