Description and Introduction

Octal D-type Transparent Latches With 3-State Outputs The SNJ54HCT373J is a high-speed octal transparent latch manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Logic Type:** Octal Transparent Latch with 3-State Outputs  
- **Technology:** HCT (High-Speed CMOS, TTL-Compatible)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Output Current:** ±6mA  
- **Propagation Delay:** 24ns (typical)  
- **Input Capacitance:** 3pF (typical)  
- **Package Type:** Ceramic DIP (20-pin)  

### **Descriptions:**  
- The SNJ54HCT373J is designed for bus-oriented applications, providing 3-state outputs for interfacing with common bus lines.  
- It features eight D-type latches with separate input (D) and output (Q) pins, controlled by a latch enable (LE) and output enable (OE) signal.  
- The device is radiation-hardened and qualified for military applications.  

### **Features:**  
- **Octal Transparent Latches:** Stores data on the rising edge of the latch enable (LE) signal.  
- **3-State Outputs:** Allows direct connection to a bus, with high-impedance state when disabled.  
- **TTL-Compatible Inputs:** Works with both CMOS and TTL logic levels.  
- **High Noise Immunity:** Typical CMOS noise margin of 0.9V at VCC = 5V.  
- **Low Power Consumption:** ICC = 4µA (max) at TA = 25°C.  
- **Military Qualified:** Meets MIL-PRF-38535 standards.  

This information is based on TI's official datasheet for the SNJ54HCT373J.
