Description and Introduction

16 x 5 asynchronous FIFO memory The SN74ALS233BN is a 10-bit transparent latch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Transparent Latch  
- **Number of Bits:** 10  
- **Output Type:** Tri-State  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Output Current (IOH):** -2.6mA  
- **Low-Level Output Current (IOL):** 24mA  
- **Propagation Delay (tpd):** 12ns (max)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 20-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions and Features:**  
- **Tri-State Outputs:** Allows multiple devices to share a common bus.  
- **Transparent Latching:** Data passes through when the latch enable (LE) is high and is held when LE is low.  
- **Wide Operating Voltage:** Supports standard 5V logic levels.  
- **High-Speed Operation:** Suitable for high-performance digital systems.  
- **Industrial Standard:** Compatible with TTL logic levels.  

This device is commonly used in bus interface applications, data storage, and signal buffering.

Application Scenarios & Design Considerations

Alternative Part Number

  • 74ALS233N --: Same 74ALS octal D-type flip-flop function and DIP-20 package, pin-compatible drop-in replacement from an alternate vendor.
  • DM74ALS233N --: Equivalent ALS-family octal flip-flop with identical logic function and pinout in a standard DIP-20 package.
  • SN74ALS273N --: Same ALS octal D-type flip-flop family and DIP-20 pinout; check output enable/clear pin differences before substitution.
  • 74ALS233BN --: Same 74ALS233 octal D-type latch function and pinout from an alternate vendor, direct functional drop-in.
  • DM74ALS233BN --: Equivalent ALS-series octal latch with identical logic function and DIP package, widely available second source.
  • SN74ALS373N --: Octal transparent D-type latch in the same ALS family and DIP package; similar function but verify pinout and enable polarity before substitution.
