Description and Introduction

Octal D-Type Edge-Triggered Flip-Flops with 3-State Outputs Here are the factual details about the **SN74AC374DBR** from **Texas Instruments (TI)**:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** SN74AC374DBR  
- **Type:** Octal D-Type Flip-Flop with 3-State Outputs  
- **Technology:** Advanced CMOS (AC)  
- **Supply Voltage Range:** 2 V to 6 V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** SSOP (Shrink Small-Outline Package)  
- **Pin Count:** 20  
- **Output Type:** 3-State (Tri-State)  
- **Logic Family:** 74AC  
- **Propagation Delay:** Typically 6.5 ns at 5V  
- **Input/Output Compatibility:** TTL-Compatible  

### **Descriptions:**
- The **SN74AC374DBR** is an octal edge-triggered D-type flip-flop with 3-state outputs.  
- It features a common clock (CLK) and output enable (OE) control.  
- Data on the D inputs is transferred to the outputs on the positive edge of the clock.  
- The outputs are in a high-impedance state when OE is high.  
- Designed for bus-oriented applications where multiple devices share a common bus.  

### **Features:**
- **Octal (8-Bit) Flip-Flop** with 3-State Outputs  
- **Positive-Edge Triggered Clocking**  
- **Bus-Structured Pinout**  
- **3-State Outputs for Bus Interface**  
- **Balanced Propagation Delays**  
- **Low Power Consumption** (AC Technology)  
- **ESD Protection** Exceeds 2000 V per JESD 22  
- **Wide Operating Voltage Range (2V to 6V)**  
- **Latch-Up Performance** Exceeds 250 mA per JESD 17

Application Scenarios & Design Considerations

Octal D-Type Edge-Triggered Flip-Flops with 3-State Outputs

Alternative Part Number

  • MC74AC374DTR2G --: Octal D-type flip-flop with 3-state outputs, same AC logic family and TSSOP package, pin-compatible and widely available.
  • 74AC374MTCX --: Functionally equivalent octal D flip-flop with 3-state outputs in TSSOP, direct drop-in replacement for the SN74AC374DBR.
  • CD74AC374M96 --: Same manufacturer AC-family octal D flip-flop with 3-state outputs; SOIC package instead of TSSOP, suitable when board space allows.
  • 74AC374SCX --: Same 74AC374 octal D flip-flop function with 3-state outputs, wide supply range, and similar speed; available in SOIC package as a direct functional replacement.
  • MC74AC374DWR2G --: Pin-compatible octal D-type flip-flop with 3-state outputs in SOIC-20 wide body, matching the AC family logic and drive characteristics.
  • CD74AC374M --: Same AC-family octal D flip-flop from TI with identical logic function and 3-state outputs, offered in SOIC package for drop-in use where package width allows.
