Description and Introduction

OCTAL D-TYPE FLIP-FLOPS WITH CLEAR The SN74AHCT273DGVR is a part manufactured by Texas Instruments (TI-PB).  

**Specifications:**  
- **Type:** Octal D-type flip-flop with clear  
- **Technology:** AHCT (Advanced High-Speed CMOS with TTL-Compatible Inputs)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** TVSOP (DGVR) - 20-pin  
- **Output Type:** Standard  
- **Clock Frequency:** Up to 100 MHz  
- **Propagation Delay:** 7.5 ns (typical)  
- **Input/Output Compatibility:** TTL-level inputs, CMOS-level outputs  
- **Current - Output High, Low:** ±8 mA  

**Descriptions:**  
The SN74AHCT273DGVR is an octal D-type flip-flop featuring a common clock (CP) and a master reset (MR) input. It is designed for high-speed, low-power operation while maintaining compatibility with TTL logic levels.  

**Features:**  
- 8-bit positive-edge-triggered flip-flops  
- Buffered common clock and asynchronous clear  
- TTL-compatible inputs  
- Balanced propagation delays  
- High noise immunity  
- Low power consumption  
- Supports live insertion  

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

Application Scenarios & Design Considerations

OCTAL D-TYPE FLIP-FLOPS WITH CLEAR

Alternative Part Number

  • MC74VHCT273ADTR2G --: Octal D-type flip-flop with clear in the same AHCT/VHCT speed class, offered in TSSOP and widely available as a direct functional replacement.
  • 74AHCT273PW,118 --: Octal D-type flip-flop with asynchronous clear, AHCT family compatible with TTL input levels, available in TSSOP package.
  • CD74HCT273M96 --: HCT octal D-type flip-flop with clear from the same vendor, TTL-compatible inputs and similar drive, usable when TSSOP is not mandatory.
  • 74AHCT273D,118 --: Same AHCT273 logic function in SOIC-20 package; pin-compatible logic alternative if package footprint can be adjusted.
