MM74HC241N DIP Octal Buffer With Noninverted Three-State Outputs

Description

MM74HC241N DIP
Octal Buffer
With Noninverted Three-State Outputs

The
M74HC241
is a high-speed CMOS integrated circuit functioning as an octal buffer and line driver with non-inverting three-state outputs. Fabricated using silicon-gate C²MOS technology, it combines the high-speed performance typically associated with LSTTL logic families with the very low power consumption inherent to CMOS circuitry. This device contains eight individual buffers, organized into two groups of four, allowing it to manage and drive multiple data lines simultaneously within a digital system.

A key feature of this IC is its three-state output capability. Each output can be in a standard logic high, a standard logic low, or a high-impedance (Hi-Z) state. This third state allows the output to be effectively disconnected from the bus, enabling multiple devices to share a common data line without electrical conflict. The outputs are non-inverting, meaning the logic level at the output matches the logic level present at the input when the device is enabled.

The device features complementary output enable controls; one active-low and one active-high, with each control pin governing a separate group of four buffers. This provides flexible control for bidirectional bus interfaces and other complex bus management tasks. All inputs are equipped with protection circuits against static discharge and transient voltage, enhancing the robustness and reliability of the device in real-world operating environments.
