Description and Introduction

FAST CMOS OCTAL TRANSPARENT LATCHES The IDT74FCT373P is an octal transparent latch manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Octal Transparent Latch  
- **Technology:** FCT (Fast CMOS TTL-Compatible)  
- **Number of Bits:** 8 (Octal)  
- **Supply Voltage (Vcc):** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** 3-State  
- **Propagation Delay:** Typically 5.5 ns  
- **Input/Output Compatibility:** TTL-Level  
- **Package Type:** 20-pin DIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The IDT74FCT373P is a high-speed, low-power octal transparent latch designed for bus-oriented applications. It features 3-state outputs for direct interface with bus lines and is compatible with TTL logic levels.  

### **Features:**  
- **High-Speed Operation:** Optimized for performance with minimal propagation delay.  
- **Low Power Consumption:** CMOS technology ensures reduced power usage.  
- **3-State Outputs:** Allows for bus sharing and reduces system loading.  
- **TTL-Compatible Inputs/Outputs:** Ensures seamless integration with TTL logic families.  
- **Latch Enable (LE) Control:** Transparent latching when LE is high; holds data when LE is low.  
- **Output Enable (OE) Control:** Disables outputs when OE is high, enabling bus isolation.  

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

Application Scenarios & Design Considerations

FAST CMOS OCTAL TRANSPARENT LATCHES

Alternative Part Number

  • SN74F373N --: Pin-compatible octal D-type transparent latch in a DIP-20 package with equivalent FCT/F logic speed and function.
  • MC74F373N --: Same octal transparent latch function and DIP-20 pinout, direct drop-in replacement for the FCT373.
  • 74F373N --: Standard 74F octal latch with identical pinout and logic function, suitable as a functional substitute.
  • CY74FCT373TPC --: Same FCT 373 octal transparent latch function with compatible pinout and speed, from a different series prefix, widely available as a drop-in replacement.
