STMicroelectronics M74HC354B1: 8-bit Multiplexer/Register
The M74HC354B1 is a high-speed CMOS 8-bit multiplexer/register manufactured by STMicroelectronics, designed to handle multiple digital data sources in your electronic projects. This integrated circuit is part of the HC family, which ensures a balance between speed and power consumption, making it suitable for a wide range of applications, from consumer electronics to complex computing systems.
This device features two distinct sections: an 8-bit multiplexer and an 8-bit edge-triggered register. The multiplexer section allows the selection of one out of eight data sources, which can be effectively channeled through a common output path under the control of the address inputs. The register section captures the data from the multiplexer on the rising edge of the clock signal, ensuring stable and reliable data handling.
The M74HC354B1 operates with a supply voltage range of 2V to 6V, providing great flexibility in terms of compatibility with other logic families and power requirements. Its low power consumption is particularly advantageous for battery-operated devices where energy efficiency is paramount.
The device is housed in a 20-pin package, offering a compact solution for space-constrained applications. It also features a built-in control line for output enable, which allows the output to be maintained in a high-impedance state, thereby preventing bus contention in systems that share common data lines.
With its high noise immunity and the ability to drive up to 10 LSTTL loads, the M74HC354B1 is a robust choice for digital multiplexing tasks. The logic levels are compatible with standard CMOS outputs and with a wide range of TTL inputs, making it easy to integrate into existing designs without additional interfacing components.
Whether you're designing a complex data routing system or simply need a reliable way to select between multiple digital inputs, the M74HC354B1 from STMicroelectronics offers a versatile and high-performance solution that can meet a variety of technical requirements.
