Frequently Asked Questions
What is the output drive current of the SN74HCT541DWR?
The SN74HCT541DWR can sink 8mA (IOL) and source 8mA (IOH) per output, making it suitable for driving standard TTL and CMOS loads. Its 3-state outputs can also be placed in high-impedance mode via the dual OE pins.
How do the output enable pins work on the SN74HCT541DWR?
The SN74HCT541DWR has two active-low output enable pins (OE1 and OE2). When either pin is driven HIGH, all eight outputs enter a high-impedance (3-state) condition, effectively disconnecting the device from the bus without affecting the input signals.
What are common applications for the SN74HCT541DWR?
Common applications include data bus buffering in microprocessor systems, memory address driving, industrial I/O expansion, and signal isolation in communication hardware. Its HCT family ensures compatibility with both 5V CMOS and TTL logic levels.
Is the SN74HCT541DWR RoHS compliant and what package does it come in?
Yes, the SN74HCT541DWR is fully RoHS compliant and lead-free (Pb-free, JESD-609 e4). It comes in a 20-pin Wide Body SOIC (PDSO-G20) package, which is suitable for automated SMT assembly on standard PCBs.
