SN74ALS241CDWR - Logic – Buffers, Drivers, Receivers, Transceivers

The SN74ALS241CDWR is an advanced logic-level, open-collector driver. It is part of the Texas Instruments ALS241CDWR family, a popular family of integrated circuits used for data communication and other high-speed applications. The SN74ALS241CDWR is designed to operate with VCC range of 2.7V to 5.5V, with a static operating current at 0V to 4.6V of maximum 30mA.

Application Field

The SN74ALS241CDWR is used in a wide range of interfacing and communications devices, such as digital logic drivers, multiplexers, transceivers, and bus interfaces. It is designed for use in devices such as computers, telecommunication systems, and industrial control systems. It can also be used in low-speed or high-speed applications and is generally considered suitable for applications that require speed and reliability.

Working Principle

The SN74ALS241CDWR is based on open-collector logic. Open-collector logic means that there is an external pull-up resistor that is connected between the output and the supply voltage. When an output is turned on, the voltage drop across the pull-up resistor forces the output voltage to rise. When an output is turned off, there is no voltage drop and the output voltage remains high.

The SN74ALS241CDWR is designed to be used as a driver in active HIGH logic circuits, where a logic 1 on the inputs will activate the output. When the input is low (logic 0), the output will remain off and the output polarity is determined by the external pull-up resistor. The SN74ALS241CDWR offers protection diodes on the input side and is suited for extended temperature ranges up to +125oC.

The SN74ALS241CDWR also offers various device-specific features such as ESD protection up to 2kV, active-high logic, pull-up resistor selectable from 2k to 4k, output off-state voltage from 2 to 5.5V, a wide supply voltage range of 2.7V to 5.5V, low static power consumption, and low quiescent current. It also offers various operating modes such as open-collector, bus-hold, and tri-state.

In conclusion, the SN74ALS241CDWR is an advanced logic-level open-collector driver designed for data communication and other high-speed applications. It offers an extended temperature range and excellent protection features, as well as low static power consumption and low quiescent current. The SN74ALS241CDWR is a powerful and reliable device for high-speed data communication and interfacing applications.
