STMicroelectronics T74LS273BI Octal D-Type Flip-Flop

The T74LS273BI is a high-performance integrated circuit produced by STMicroelectronics, designed to meet the needs of a wide range of digital applications. This device belongs to the 74LS family, which is well-known for its low-power Schottky technology, offering a perfect balance between speed and power consumption.

The T74LS273BI is an octal D-type flip-flop with a clear function. It consists of eight edge-triggered flip-flops with individual D-type inputs and Q outputs. The clear input is shared among all flip-flops and is active low, meaning that when the clear input is pulled low, all the flip-flops are set to a low state, regardless of the clock input or data inputs. This feature is particularly useful for initializing registers and counters in digital systems.

Each flip-flop is designed to store a single bit of data and will change state on the rising edge of the clock input. This makes the T74LS273BI ideal for applications that require data storage, data transfer, or the synchronization of multiple bits of data. The device is commonly used in buffer registers, control registers, and state machines, among other digital logic applications.

The T74LS273BI is packaged in a 20-pin DIP (Dual In-line Package), making it suitable for through-hole mounting, which is beneficial for prototyping and educational purposes. The device also features a wide operating temperature range, ensuring reliable performance in various environmental conditions.

Key specifications of the T74LS273BI include:

• Supply Voltage: Typically 5V
• Low Power Consumption: Schottky technology
• High-Speed Operation
• Output Drive Capability: Capable of driving 15 LSTTL loads
• Input Clamp Diodes: Limits high-speed termination effects

STMicroelectronics ensures that the T74LS273BI meets high-quality standards, providing designers with a robust and reliable component for their digital systems. Whether you are working on data processing, control systems, or any application requiring a stable and efficient flip-flop, the T74LS273BI is an excellent choice to consider.
