Description and Introduction

Octal D-Type Transparent Latches with 3-state Outputs The SN74ALS373ADBR is a transparent D-type latch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Transparent Latch  
- **Number of Bits:** 8  
- **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 Time (tpd):** 12ns (max) at 5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** SSOP-20 (DBR)  

### **Descriptions:**  
The SN74ALS373ADBR is an octal transparent latch with 3-state outputs. It is designed for bus-organized systems and features a latch-enable (LE) input and an output-enable (OE) input. When LE is high, the data inputs (D0-D7) are latched to the outputs (Q0-Q7). When OE is low, the outputs are active; when high, they are in a high-impedance state.  

### **Features:**  
- **Octal D-Type Transparent Latches**  
- **3-State Outputs for Bus Interface**  
- **Buffered Control Inputs**  
- **Typical Propagation Delay of 8ns**  
- **ESD Protection Exceeds 2000V**  
- **Wide Operating Voltage Range (4.5V to 5.5V)**  
- **Compatible with TTL Input and Output Levels**  

This latch is commonly used in memory address latching, data buffering, and I/O port applications.
