Frequently Asked Questions
What is the SN74HC241DWE4 and what does it do?
The SN74HC241DWE4 is an octal non-inverting buffer and line driver from Texas Instruments' HC CMOS logic family. It features eight buffer/driver channels with 3-state outputs, allowing the outputs to be placed in a high-impedance state to enable bus sharing. It is designed to drive heavily loaded buses and long lines, with a rated load capacitance of 150 pF and supply voltage range of 2V to 6V.
What package does the SN74HC241DWE4 use and how many pins does it have?
The SN74HC241DWE4 is housed in a 20-pin Small Outline Integrated Circuit (SOIC) package, also known as the DW package in Texas Instruments nomenclature. This wide-body SOIC package is well-suited for automated PCB assembly and offers a good balance between board space and thermal performance.
How are the output-enable inputs configured on the SN74HC241DWE4?
The SN74HC241DWE4 has dual output-enable (OE) control inputs with complementary polarity: one active-low enable input and one active-high enable input. This arrangement allows flexible bus control where both inputs must be asserted in their respective active states simultaneously to enable the outputs. When either enable condition is not met, all eight outputs enter the high-impedance (3-state) condition.
What is the operating temperature range of the SN74HC241DWE4?
The SN74HC241DWE4 is rated for operation across the extended commercial and industrial temperature range of -40°C to +85°C, making it suitable for use in industrial control systems, automotive support electronics, and other applications that require reliable performance across a wide temperature span.
Is the SN74HC241DWE4 RoHS compliant and lead-free?
Yes. The 'E4' suffix in the part number indicates that the SN74HC241DWE4 meets RoHS compliance requirements and is manufactured using a lead-free, halogen-free process per Texas Instruments' green packaging standards (JESD-609 code e4). It is suitable for use in environmentally regulated end products.
