Description and Introduction

DUAL 4-BIT D-TYPE LATCHES WITH 3-STATE OUTPUTS The SN74AS873ANT is a manufacturer by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Category:** Integrated Circuits (ICs)  
- **Family:** Logic - Flip Flops  
- **Series:** 74AS  
- **Package/Case:** 20-DIP (0.300", 7.62mm)  
- **Packaging:** Tube  
- **Operating Temperature:** 0°C ~ 70°C  
- **Voltage - Supply:** 4.5V ~ 5.5V  
- **Logic Type:** D-Type Transparent Latch  
- **Number of Bits per Element:** 8  
- **Output Type:** Tri-State, Non-Inverted  
- **Current - Output High, Low:** 15mA, 48mA  
- **Trigger Type:** High Level  
- **Mounting Type:** Through Hole  

### **Descriptions:**  
The SN74AS873ANT is an 8-bit transparent latch with 3-state outputs from TI's 74AS series. It is designed for high-performance digital systems requiring fast data storage and retrieval. The device features non-inverting outputs and tri-state capability, allowing multiple devices to share a common bus.  

### **Features:**  
- **High-Speed Operation:** Optimized for AS (Advanced Schottky) performance.  
- **Tri-State Outputs:** Allows bus-oriented applications.  
- **Wide Operating Voltage:** Supports 4.5V to 5.5V.  
- **High Output Drive:** Capable of sourcing/sinking significant current (15mA high, 48mA low).  
- **Transparent Latching:** Data passes through when the enable (G) input is high.  
- **DIP Package:** Through-hole mounting for easy prototyping.  

This information is strictly based on the manufacturer's datasheet and technical specifications.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • 74F873N --: Same 8-bit D-type transparent latch function with dual 4-bit outputs, TTL-compatible pinout in DIP-24, direct functional replacement.
  • MC74F873N --: Equivalent 8-bit transparent latch with 3-state outputs in DIP-24 package, matches logic function and supply requirements.
  • SN74F873NT --: Same F-series 8-bit latch family from TI with identical function and DIP-24 pinout, though from a different logic series than the AS original.
  • CD74ACT873E --: CMOS ACT-series 8-bit latch in DIP-24 with similar logic function and pinout, offering lower power consumption.
