SN74LVCH244ADBRG4 - Texas Instruments Octal Buffer/Driver

The SN74LVCH244ADBRG4 is a high-performance, octal buffer and line driver designed to facilitate the interfacing between low-voltage, high-speed logic circuits and other voltage levels. Manufactured by Texas Instruments, this device is part of the SN74 family, which is renowned for its robustness, versatility, and efficiency in a wide range of applications.

Constructed with an advanced BiCMOS technology, the SN74LVCH244ADBRG4 is optimized for 3.3V to 5.5V VCC operation, making it ideal for systems that require a bridge between 3.3V and 5V logic without the need for direction control. This feature simplifies the design and increases system reliability by eliminating the potential for bus contention in a mixed-voltage environment.

The device features eight non-inverting buffers and drivers with 3-state outputs (D1 to D8), which can be employed as memory address drivers, clock drivers, and bus-oriented transmitters/receivers. The 3-state outputs, which are controlled by the output enable (OE) inputs, allow the outputs to be placed in a high-impedance state, thus facilitating bidirectional data flow with external pull-up/down resistors and sharing the same data lines.

Key specifications of the SN74LVCH244ADBRG4 include:

• Logic Family: LVCH
• Logic Type: Octal Buffer/Line Driver
