Description and Introduction

Octal Transparent D-Type Latches With 3-State Outputs Here are the factual details about the **SN74HCT373PWR** from **Texas Instruments**:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Category:** Integrated Circuits (ICs)  
- **Type:** Logic - Latches  
- **Subcategory:** Transparent Latch  
- **Technology:** CMOS  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** TSSOP-20  
- **Mounting Type:** Surface Mount  
- **Number of Bits:** 8  
- **Output Type:** Tri-State  
- **Logic Family:** HCT  
- **Propagation Delay Time:** 14 ns (typical)  
- **High-Level Output Current:** -6 mA

- **Input Capacitance:** 3 pF  
- **RoHS Status:** RoHS Compliant  

### **Descriptions:**
The **SN74HCT373PWR** is an octal transparent latch with 3-state outputs, designed for bus-organized systems. It features high-speed CMOS technology while maintaining low power consumption. The latch is transparent when the Latch Enable (LE) input is high, allowing data to pass through. When LE goes low, the data is latched. The Output Enable (OE) input controls the tri-state outputs, allowing multiple devices to share a common bus.

### **Features:**
- **Octal D-Type Transparent Latch** with 3-state outputs  
- **Compatible with TTL Inputs** (HCT family)  
- **Wide Operating Voltage Range:** 4.5V to 5.5V  
- **Low Power Consumption:** ICC = 4 μA (max)  
- **High Noise Immunity**  
- **Balanced Propagation Delays**  
- **ESD Protection:** Exceeds 2000V per JESD 22  
- **Bus-Structured Pinout**  
- **Available in TSSOP-20 Package**

Application Scenarios & Design Considerations

Octal Transparent D-Type Latches With 3-State Outputs

Alternative Part Number

  • MC74HCT373ADTR2G --: Octal D-type transparent latch with 3-state outputs, HCT logic family, TSSOP package, functionally equivalent to SN74HCT373PWR.
  • 74HCT373D --: HCT octal transparent latch with 3-state outputs in SOIC package; same logic function and compatible voltage levels.
  • CD74HCT373M --: Same manufacturer HCT octal latch with 3-state outputs, SOIC package, direct functional replacement for the TSSOP version.
  • 74HCT373PW,118 --: Same 74HCT373 function and TSSOP package, widely available second-source with equivalent logic thresholds and drive.
  • CD74HCT373M96 --: TI HCT-family octal transparent latch with tri-state outputs; same logic function, though in SOIC package so footprint differs from TSSOP.
