Description and Introduction

Octal D-Type Edge-Triggered Flip-Flops The SN74BCT374N is an octal edge-triggered D-type flip-flop with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Flip-flop  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage Supply:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** PDIP-20  
- **Mounting Type:** Through Hole  
- **Propagation Delay Time:** 12 ns (max)  
- **High-Level Output Current:** -15 mA  
- **Low-Level Output Current:** 64 mA  
- **Logic Family:** BCT  

### **Descriptions and Features:**  
- **Octal Flip-Flop:** Contains eight D-type flip-flops with individual D inputs and Q outputs.  
- **3-State Outputs:** Allows outputs to be placed in a high-impedance state for bus-oriented applications.  
- **Edge-Triggered Clocking:** Data is transferred on the low-to-high transition of the clock (CLK) input.  
- **Buffered Control Inputs:** Includes a buffered output-enable (OE) input for disabling outputs.  
- **Bus Interface:** Designed for driving highly capacitive or relatively low-impedance loads.  
- **TTL-Compatible Inputs:** Ensures compatibility with TTL logic levels.  
- **Wide Operating Voltage:** Supports standard 5V operation.  

This device is commonly used in data storage, buffering, and bus interface applications.

Application Scenarios & Design Considerations

Octal D-Type Edge-Triggered Flip-Flops

Alternative Part Number

  • 74F374PC --: Octal D-type flip-flop with 3-state outputs in the same 20-pin DIP package and pinout; faster F-series logic is a common drop-in for BCT374 in many designs.
  • MC74ACT374N --: ACT-series octal D flip-flop with 3-state outputs, 20-pin DIP, TTL-compatible inputs and similar drive characteristics to the BCT374.
  • CD74HCT374E --: HCT-series octal D-type flip-flop with 3-state outputs in 20-pin DIP; same function and pinout, suitable when slightly lower speed is acceptable.
  • 74BCT374APC --: Same octal D-type flip-flop function with 3-state outputs in a DIP-20 package, pin-compatible with the original BCT374.
