STMicroelectronics M74HCT651B1N Integrated Circuit

The M74HCT651B1N is a high-performance integrated circuit designed and manufactured by STMicroelectronics, a global leader in semiconductor solutions. This IC is part of the HCT (High-Speed CMOS with TTL levels) family, which ensures compatibility with both CMOS and TTL logic levels, making it a versatile choice for interfacing in mixed-technology environments.

At the core of the M74HCT651B1N are eight bidirectional transceivers and latch functions that are suitable for multiplexed data transmission of bus-oriented systems. The transceivers provide the dual function of a transmitter and a receiver, both of which operate independently but share the same data path. This allows for efficient data flow in either direction, which is essential for modern digital communication systems.

Key Features:

• Logic Type: Transceiver, Non-Inverting
• Number of Bits: 8 bits per channel
• Output Current: High-level output current of -6 mA, Low-level output current of 6 mA
• Supply Voltage: Operates at 5V, with a tolerance that allows for use in 5V logic systems
• Operating Temperature: Ranges from -55°C to 125°C, providing reliability in various environmental conditions

The M74HCT651B1N also features a latch-enable (LE) input and an output-enable (OE) input, which add an extra layer of control over the data flow. The LE input allows the user to latch the data present on the inputs, while the OE input enables the outputs, ensuring that data is transmitted only when required.

With a pin count of 24, this IC comes in a DIP (Dual In-line Package), which is widely used and easy to handle in various types of PCB (Printed Circuit Board) designs. The DIP package also facilitates easy insertion and removal, which is beneficial for prototyping and testing phases.

The M74HCT651B1N is characterized for operation from -55°C to 125°C, ensuring its performance in extreme conditions and making it suitable for industrial and automotive applications where robustness and reliability are crucial.

In summary, the M74HCT651B1N from STMicroelectronics is a highly functional and reliable component for digital communication systems, offering the flexibility and performance required for complex electronic designs.
