Flip Flops datasheet and documents for SN74ABT273N
Flip Flops Overview
The SN74ABT273N is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the ABT logic series. It features eight non-inverting outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The component exhibits a propagation delay of 6.8 ns, with high-level output current capability of -32 mA and low-level output current of 64 mA. It utilizes a 20-pin PDIP package for through-hole mounting and supports a wide operating temperature range from -40°C to +85°C.
Flip Flops Feature Summary
- Integrates eight edge-triggered D-type flip-flops with positive-edge clocking for synchronous data storage.
- Provides strong push-pull output drivers capable of driving standard TTL loads directly.
- Features a master reset function that forces all outputs to a low state independently of the clock signal.
Flip Flops Applications
- Registering eight-bit data words in digital systems.
- Implementing parallel-to-serial or serial-to-parallel data conversion interfaces.
- Creating temporary memory buffers in microprocessor-based architectures.
Flip Flops Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and environmental compliance. Confirm that the procurement channel provides valid traceability for the component lot. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing orders.
Flip Flops Selection Notes
Select this component when high-speed switching is required alongside robust drive strength for TTL-compatible loads. The ABT series offers superior performance compared to older LS or ALS families while maintaining compatible pinouts. Ensure the application environment stays within the specified voltage and temperature limits for reliable operation.
Flip Flops Part Context
This device is part of the broader 74ABT family of high-speed CMOS logic products. It serves as a direct functional replacement for legacy octal flip-flops like the 74LS273 but with significantly faster switching speeds and improved power efficiency. The PDIP-20 package ensures compatibility with traditional through-hole PCB layouts.
