Frequently Asked Questions
What is the maximum output sink current of the SN74LS05D?
The SN74LS05D has a maximum output sink current (I_OL) of 8mA (0.008A). This open-collector output allows the device to pull a logic node low when active, making it suitable for driving LEDs, relays, and wired-AND bus lines within safe current limits.
What are the typical applications of the SN74LS05D hex inverter?
The SN74LS05D is commonly used for logic signal inversion, open-collector bus interfacing, interrupt request lines, and level-shifting between different voltage domains up to 5.5V. Its six independent channels make it ideal for microcontroller I/O expansion, relay drivers, LED drivers, and wired-AND configurations in industrial control, telecommunications, and embedded systems.
Is the SN74LS05D RoHS compliant and what package does it come in?
Yes, the SN74LS05D is RoHS-compliant with a Pb-free (lead-free) construction, indicated by the Pbfree Code 'Yes' and JESD-609 code e4. It is packaged in a 14-pin Small Outline IC (SOIC) package (JESD-30 code R-PDSO-G14), offering a compact footprint suitable for surface-mount assembly in space-constrained PCB designs.
What is the difference between the SN74LS05D and SN74LS04D?
The SN74LS05D features open-collector outputs, while the SN74LS04D has standard totem-pole (push-pull) outputs. Open-collector outputs on the SN74LS05D require an external pull-up resistor but enable wired-AND bus connections and output voltage levels exceeding the supply voltage, making the SN74LS05D more flexible for mixed-voltage and bus-sharing applications.
