Description and Introduction

Octal Transparent D-Type Latches With 3-State Outputs The SN74LVC373ADBR is a part manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Category:** Logic - Latches  
- **Package / Case:** SSOP-20  
- **Packaging:** Tape & Reel (TR)  
- **Logic Type:** D-Type Transparent Latch  
- **Number of Bits:** 8  
- **Output Type:** Tri-State  
- **Voltage - Supply:** 1.65V to 3.6V  
- **Operating Temperature:** -40°C to 85°C  
- **Mounting Type:** Surface Mount  
- **Input Capacitance:** 3.5pF (typical)  
- **Propagation Delay Time (tpd):** 5.3ns (max) at 3.3V  
- **Output Current:** ±24mA  

### **Descriptions:**
- The SN74LVC373ADBR is an octal transparent latch with 3-state outputs designed for 1.65V to 3.6V VCC operation.  
- It features a latch-enable (LE) input and an output-enable (OE) input for controlling data flow.  
- When LE is high, the Q outputs follow the data (D) inputs. When LE is low, the outputs are latched.  
- The outputs are placed in a high-impedance state when OE is high.  

### **Features:**
- **Wide Operating Voltage Range:** 1.65V to 3.6V  
- **Supports Mixed-Mode Voltage Operation**  
- **3-State Outputs for Bus-Oriented Applications**  
- **Ioff Supports Partial-Power-Down Mode Operation**  
- **Latch-Up Performance Exceeds 250mA per JESD 17**  
- **ESD Protection Exceeds JESD 22**  
  - 2000V Human Body Model (A114-A)  
  - 1000V Charged Device Model (C101)  

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

Application Scenarios & Design Considerations

Octal Transparent D-Type Latches With 3-State Outputs

Alternative Part Number

  • MC74LCX373DTR2G --: Octal transparent D-type latch with 3-state outputs in the same LVC-family logic, TSSOP package, direct functional and electrical equivalent.
  • 74LVC373APW,118 --: Same 74LVC373 octal latch function with 3-state outputs, TSSOP-20 package, widely available second source with matching logic levels.
  • SN74LVC573APWR --: Same LVC family octal transparent latch with 3-state outputs; the 573 differs only in pinout (inputs on opposite side), so it is a close functional substitute when layout allows.
