Description and Introduction

Quadruple D-Type Positive-Edge-Triggered Flip-Flops With Clear The SN74AS175B is a quad D-type flip-flop with clear, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Flip-flop  
- **Number of Bits:** 4  
- **Output Type:** Differential  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Output Current (IOH):** -15mA  
- **Low-Level Output Current (IOL):** 48mA  
- **Propagation Delay Time (tpd):** 8ns (typical)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** PDIP-16, SOIC-16, CDIP-16  

### **Descriptions:**  
- The SN74AS175B features four edge-triggered D-type flip-flops with individual data inputs (D) and complementary outputs (Q and Q̅).  
- A common clock (CLK) and clear (CLR) input synchronously control all flip-flops.  
- The device operates in positive-edge-triggered mode, meaning data is transferred to outputs on the rising edge of the clock pulse.  

### **Features:**  
- **Edge-Triggered Operation:** Ensures stable data transfer on clock rising edge.  
- **Common Clock and Clear:** Simplifies synchronous control.  
- **Complementary Outputs:** Provides both true (Q) and inverted (Q̅) outputs.  
- **High-Speed Performance:** Low propagation delay for fast operation.  
- **Wide Operating Voltage:** Supports standard TTL levels (5V).  
- **Buffered Inputs:** Improves noise immunity.  

This device is commonly used in digital systems for data storage, synchronization, and state control applications.

Application Scenarios & Design Considerations

Quadruple D-Type Positive-Edge-Triggered Flip-Flops With Clear

Alternative Part Number

  • MC74ACT175N --: Quad D flip-flop with clear, functionally equivalent to SN74AS175B, available from a different manufacturer and series.
  • CD74ACT175E --: Same logic function in the ACT family with compatible pinout, offering a lower-power CMOS alternative to the AS device.
  • 74ACT175PC --: Pin-compatible quad D flip-flop with clear, suitable drop-in replacement with similar speed and drive characteristics.
  • MC74AC175N --: Quad D flip-flop with clear, functionally equivalent to SN74AS175B, widely available and pin-compatible in DIP packages.
  • 74HC175N --: Quad D flip-flop with clear in HC logic family, suitable drop-in alternative when slightly lower speed is acceptable.
