The SN74AC241N is an octal buffer/line driver with tri-state outputs. The device is organized as two 4-bit sections, with a separate output-enable (OE) input for each section. When OE is high, the corresponding outputs go into a high-impedance OFF-state. The SN74AC241N device is designed to be used with other logic families, such as the TTL family but especially with CMOS logic families as it offers very low power dissipation over wide ranges of VCC and temperature.

Application Field

The SN74AC241N is suitable for a wide range of applications. The buffer/line driver has a broad range of uses for computer, communication, motor control and various other industrial electronic equipment. It has applications such as monitoring multiple status operations on the same data bus, using tri-state to decode shared bus applications and creating an output of signals from multiple logic sources.

The SN74AC241N buffer/line driver also allows for a high fan-out to loads and its outputs can be connected together to act as a bus among several systems. This device operates over a wide temperature range and provides a capability of running at high speed with minimal power dissipation.

Working Principle

The SN74AC241N buffer/line driver is designed to buffer data in both directions. The device features an output-enable (OE) input for each section. When OE is high, the corresponding outputs go into a high-impedance OFF-state. This tri-state buffer can be used for connecting various peripherals and CPUs. When the inputs of the buffer/line driver are low, the corresponding outputs are low; otherwise, the outputs are high.

The SN74AC241N operates with a power supply ranging from 4.5 V to 5.5 V and provides a capability of running at high speed with minimal power dissipation. The device is tolerant of supply voltages up to 6.5 V, for further flexibility. The SN74AC241N is characterized for operation over the extended commercial temperature range of 0°C to 70°C.

This buffer/line driver is designed to drive a wide range of TTL and CMOS loads, taking advantage of its wide voltage, low current, and low power dissipation characteristics as it is optimized for CMOS technology. The SN74AC241N features non-inverting bus drivers. It has a very low noise and low propagation delay, making it especially suited for bus driving applications requiring a low-impedance environment.

Conclusion

The SN74AC241N is an octal buffer/line driver with tri-state outputs, suitable for a wide range of applications including monitoring multiple status operations, using tri-state to decode shared bus applications and creating an output of signals from multiple logic sources. It has a wide fan-out to loads and its outputs can be connected together to act as a bus among several systems. This device operates with a power supply from 4.5 V to 5.5 V and is characterized for operation over an extended commercial temperature range of 0°C to 70°C, with minimum power dissipation.
