Description and Introduction

Octal D-Type Transparent Latches With 3-State Outputs The SN74ALS573CDWR is a part manufactured by Texas Instruments (TEXAS). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Category:** Logic - Latches  
- **Type:** Octal Transparent D-Type Latch with 3-State Outputs  
- **Package / Case:** SOIC-20 (Wide)  
- **Mounting Type:** Surface Mount  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage - Supply:** 4.5V to 5.5V  
- **Operating Temperature:** 0°C to 70°C  
- **Logic Family:** ALS  
- **Propagation Delay Time:** 12 ns (max)  
- **High-Level Output Current:** -15 mA  
- **Low-Level Output Current:** 24 mA  

### **Descriptions:**  
The SN74ALS573CDWR is an octal transparent D-type latch with 3-state outputs designed for bus-organized systems. It features a latch enable (LE) input and an output enable (OE) input for controlling data flow. When LE is high, the outputs follow the data inputs. When LE transitions low, the data is latched. The outputs can be placed in a high-impedance state using the OE input.  

### **Features:**  
- **Octal D-Type Latch** with 3-state outputs  
- **Bus-Structured Pinout** for easy PCB layout  
- **High-Speed Operation** (12 ns max propagation delay)  
- **Wide Operating Voltage Range** (4.5V to 5.5V)  
- **3-State Outputs** for bus interfacing  
- **ESD Protection** exceeds 2000V per MIL-STD-883  
- **Compatible with TTL Inputs**  

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

Application Scenarios & Design Considerations

Octal D-Type Transparent Latches With 3-State Outputs

Alternative Part Number

  • 74ALS573CDWR --: Same 74ALS octal D-type transparent latch function in SOIC-20 wide body, pin-compatible and drop-in replacement.
  • DM74ALS573CWM --: Octal D-type latch with 3-state outputs in the same ALS logic family and SOIC package, functionally equivalent.
  • CD74ACT573M --: Octal transparent D-type latch with 3-state outputs in SOIC-20; ACT family offers similar speed with CMOS input levels, suitable functional substitute.
  • 74ACT573SCX --: Octal D-type transparent latch with 3-state outputs in SOIC-20 wide body, functionally equivalent to the SN74ALS573 and pin-compatible in most designs.
  • MC74ACT573DWR2G --: Octal transparent latch with 3-state outputs, same 20-pin SOIC wide package and function, ACT family offers similar speed with CMOS input levels.
  • CD74ACT573M96 --: TI octal D-type transparent latch with 3-state outputs in SOIC-20, same logic function and package style, ACT family provides comparable performance.
