Description and Introduction

16 × 5 ASYNCHRONOUS FIRST-IN, FIRST-OUT MEMORY The SN74ALS229BN is a 9-bit parity generator/checker manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Parity Generator/Checker  
- **Number of Bits:** 9  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** PDIP-16  
- **Propagation Delay Time:** 12ns (typical)  
- **Output Type:** TTL-Compatible  

### **Descriptions:**  
The SN74ALS229BN is designed to generate or check parity for 9-bit data words. It can be configured for even or odd parity operation and includes cascading inputs for expansion to larger word sizes.  

### **Features:**  
- **9-bit parity generator/checker**  
- **Even or odd parity selection**  
- **Cascading inputs for expansion**  
- **TTL-compatible inputs and outputs**  
- **Low power consumption**  
- **Standard 16-pin DIP package**  

This information is based solely on the device's technical specifications from TI.

Application Scenarios & Design Considerations

16 × 5 ASYNCHRONOUS FIRST-IN, FIRST-OUT MEMORY

Alternative Part Number

  • 74ALS229N --: Same 74ALS229 function (16x4 or 16x5 FIFO register) in a DIP-20 package, pin-compatible with the SN74ALS229BN and available from an alternate vendor.
  • SN74ALS229BDW --: Same ALS229 FIFO function from TI in a SOIC-20 wide-body package; electrically equivalent, suitable when a surface-mount footprint is acceptable.
  • SN74ALS229BNSR --: TI ALS229 FIFO in a SOP-20 package with identical logic and timing; a drop-in functional substitute when the board supports the SOP footprint.
