Description and Introduction

Octal D-Type Transparent Latches The SN74BCT573N is an octal transparent D-type latch manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** D-Type Latch  
- **Number of Bits:** 8 (Octal)  
- **Output Type:** Tri-State  
- **Voltage Supply:** 4.5V to 5.5V  
- **High-Level Output Current:** -15mA  
- **Low-Level Output Current:** 48mA  
- **Propagation Delay Time:** 12ns (max)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** PDIP-20  

### **Descriptions:**  
- The SN74BCT573N is a high-speed, low-power octal transparent latch with 3-state outputs.  
- It is designed for bus-organized systems and features a buffered common output-enable (OE) input.  
- The latch is transparent when the latch-enable (LE) input is high, allowing data to pass through.  
- When LE is low, the data is latched.  

### **Features:**  
- **3-State Outputs:** Allows direct connection to a bus.  
- **Buffered Control Inputs:** Reduces loading effects.  
- **High Drive Outputs (-15mA IOH, 48mA IOL):** Suitable for driving heavily loaded buses.  
- **TTL-Compatible Inputs:** Ensures compatibility with TTL logic levels.  
- **ESD Protection:** Exceeds 2000V per MIL-STD-883, Method 3015.  

This device is commonly used in bus interface, memory address latching, and data buffering applications.
