Description and Introduction

16-Bit Transparent D-Type Latches With 3-State Outputs 48-SSOP -40 to 85 The SN74ABT16373 is a 16-bit transparent D-type latch manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Logic Type:** D-Type Latch  
- **Number of Bits:** 16  
- **Output Type:** 3-State  
- **Voltage Supply:** 4.5V to 5.5V  
- **High-Level Output Current:** -32mA  
- **Low-Level Output Current:** 64mA  
- **Propagation Delay Time:** 3.5ns (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 48-pin SSOP, TSSOP  

### **Descriptions:**
- The SN74ABT16373 is a high-performance, 16-bit transparent latch with 3-state outputs.  
- It is designed for bus interface applications in high-speed digital systems.  
- The device features a latch-enable (LE) input and an output-enable (OE) input for control.  

### **Features:**
- **High-Speed Operation:** Optimized for 5V operation with fast propagation delays.  
- **3-State Outputs:** Allows direct interface with bus-organized systems.  
- **Bus-Hold Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **ESD Protection:** Exceeds 2000V per JESD 22 (Human Body Model).  
- **Flow-Through Pinout:** Simplifies PCB layout and reduces noise.  
- **Latch-Up Performance:** Exceeds 500mA per JESD 78.  

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

Application Scenarios & Design Considerations

16-Bit Transparent D-Type Latches With 3-State Outputs 48-SSOP -40 to 85

Alternative Part Number

  • 74ABT16373DGGR --: Same 16-bit transparent D-type latch function from TI with equivalent ABT speed and drive, offered in a TSSOP package; a direct functional replacement with a different ordering-code format.
  • CY74FCT16373CTPVC --: FCT-series 16-bit transparent latch with comparable speed and 5V TTL-compatible I/O; pin-compatible in many designs and from a different product family.
  • 74ABT16373ADGG --: NXP ABT-family 16-bit transparent D-type latch with matching logic function and similar propagation delay, providing a second-source option from a different manufacturer.
  • CY74FCT16373T --: FCT-series 16-bit transparent latch with similar pinout and logic function, often used as a drop-in replacement for ABT16373 devices.
  • 74ABT16373CSSC --: Equivalent ABT 16-bit latch from Fairchild/onsemi, matching function and voltage range for bus-interface applications.
