Description and Introduction

DUAL 4-BIT D-TYPE LATCHES WITH 3-STATE OUTPUTS The SN54ALS873BJT is a 16-bit transparent D-type latch with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Logic Type:** D-Type Latch  
- **Number of Bits:** 16  
- **Output Type:** 3-State  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to 125°C (Military Grade)  
- **Package Type:** Ceramic Flatpack (J-Lead)  

### **Descriptions and Features:**  
- **Transparent Latching:** Data passes through when the latch enable (LE) is high and is latched when LE goes low.  
- **3-State Outputs:** Allows outputs to be in high-impedance state for bus-oriented applications.  
- **High-Speed Operation:** Part of the Advanced Low-Power Schottky (ALS) family, providing a balance of speed and power efficiency.  
- **Military-Grade Reliability:** Designed for harsh environments with extended temperature range.  
- **Bus Interface Capability:** Suitable for buffering and driving bus lines in microprocessor systems.  

This device is typically used in high-performance digital systems requiring reliable data storage and bus interfacing.

Application Scenarios & Design Considerations

DUAL 4-BIT D-TYPE LATCHES WITH 3-STATE OUTPUTS

Alternative Part Number

  • 74ALS873BN --: Same 74ALS873 function (dual 4-bit D latch) in a DIP package, pin-compatible with the JT package and widely available.
  • DM74ALS873N --: Direct functional equivalent of the ALS873 dual 4-bit latch in a plastic DIP, suitable for commercial temperature range applications.
  • SN74ALS873BN --: Commercial-grade version of the same ALS873 latch in a DIP package, offering identical logic function when military temperature range is not required.
