Description and Introduction

OCTAL TRANSPARENT D-TYPE LATCHES WITH 3-STATE OUTPUTS The SN54ALS373J is a part manufactured by Texas Instruments (TI). Here are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** SN54ALS373J  
- **Technology Family:** ALS (Advanced Low-Power Schottky)  
- **Package Type:** J (Ceramic DIP)  
- **Operating Temperature Range:** -55°C to +125°C (Military-grade)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Logic Type:** Octal Transparent D-Type Latch  
- **Number of Bits:** 8 (Octal)  
- **Output Type:** 3-State  
- **Propagation Delay:** Typically 12ns (varies with conditions)  
- **Input/Output Compatibility:** TTL  

### **Descriptions:**
The SN54ALS373J is an octal transparent latch with 3-state outputs, designed for bus-organized systems. It is part of the ALS series, which offers improved speed and power efficiency compared to standard TTL logic. The device is housed in a ceramic DIP package, making it suitable for harsh environments, including military applications.

### **Features:**
- **Octal D-Type Latch:** Stores 8 bits of data with transparent latch operation.  
- **3-State Outputs:** Allows for bus sharing and reduces bus contention.  
- **High-Speed Operation:** Low propagation delay for improved performance.  
- **Wide Operating Temperature:** Supports military-grade temperature ranges.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard TTL logic levels.  
- **Latch Enable (LE) and Output Enable (OE) Controls:** Provides flexible data latching and output control.

Application Scenarios & Design Considerations

OCTAL TRANSPARENT D-TYPE LATCHES WITH 3-STATE OUTPUTS

Alternative Part Number

  • 74ALS373N --: Same ALS octal transparent D-type latch function in a DIP package, pin-compatible with the SN54ALS373J for most applications.
  • DM74ALS373N --: Direct functional equivalent octal latch with 3-state outputs, widely available and pin-compatible.
  • CD74ACT373E --: ACT-family octal transparent latch with similar speed and pinout, usable as a drop-in substitute when slight drive/voltage differences are acceptable.
  • MC74ACT373N --: Octal transparent latch with similar logic function and DIP pinout; ACT family offers comparable speed with TTL-compatible inputs.
  • CD74HCT373E --: HCT octal transparent latch in DIP, functionally equivalent with TTL-compatible inputs, suitable when slight speed differences are acceptable.
