Description
This IC features eight D-type flip-flops, which are used to store binary data. Each flip-flop stores one bit, making the SN74LS273N suitable for applications requiring temporary data storage, such as registers in microprocessors. The device operates with a clock signal, and data is transferred from the input to the output on the positive edge of the clock pulse.
The SN74LS273N also includes a clear (CLR) input that, when activated, resets all outputs to a low state, independent of the clock. This feature is useful for initializing or resetting the stored data.
With a standard 20-pin dual in-line package (DIP), it is easy to integrate into various electronic circuits. The SN74LS273N is widely used in digital systems for tasks like data buffering, counters, and memory addressing.

Features
1. Octal D Flip-Flop: It contains eight D-type flip-flops with a common clock input, making it suitable for parallel data storage.
2. Positive-Edge Triggered: It captures data on the rising edge of the clock signal.
3. Clear Functionality: Includes an asynchronous clear input to reset all flip-flops to a low state, independent of the clock.
4. High Noise Immunity: Designed to operate reliably in environments with electrical noise.
5. TTL Compatible: Ensures compatibility with other TTL devices, supporting standard TTL voltage levels.
6. High Speed: Provides quick data processing suitable for high-speed applications.
7. Dual In-Line Package (DIP): Available in a 20-pin DIP, making it easy to use in breadboard and prototyping applications.
8. Wide Operating Temperature Range: Suitable for a variety of operating conditions.
These features make the SN74LS273N a versatile choice for applications requiring efficient data storage and transfer in digital circuits.
Pinout
- Pins 1-8: Data inputs (D0-D7) for each of the eight flip-flops.
- Pin 9: Ground (GND) connection.
- Pin 10: Clear (CLR) input, active-low, used to reset all outputs to low when asserted.
- Pin 11: Clock (CLK) input, triggers data capture on the rising edge.
- Pins 12-19: Outputs (Q0-Q7) corresponding to the data inputs.
- Pin 20: Supply voltage (VCC), typically 5V.
The SN74LS273N is commonly used in applications where data needs to be stored temporarily and requires synchronization with a clock signal.
