Overview
Description
The SN74LS273N is an integrated circuit (IC) from Texas Instruments, designed as an octal D-type flip-flop with a direct clear function. It belongs to the 74LS series, which is known for its low-power Schottky TTL (Transistor-Transistor Logic) technology, providing fast switching speeds while consuming less power.
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.

Pinout
The SN74LS273N is a 20-pin integrated circuit that functions as an octal D-type flip-flop with a clear function. Each of the eight flip-flops in the chip operates independently and is positive-edge triggered, meaning data is captured on the rising edge of the clock input. Here's a concise breakdown of its pin functions:
- 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.
