Frequently Asked Questions
What is the output drive current of the SN74ACT241NSR?
The SN74ACT241NSR can sink up to 24 mA (IOL) and source up to 15 mA (IOH), making it capable of driving standard TTL loads and long PCB traces at 5 V supply voltage with the ACT logic family.
How does the output enable control work on the SN74ACT241NSR?
The device has two output-enable inputs: one active-high (OE1) and one active-low (OE2). Both must be asserted appropriately to enable outputs, providing flexible control for unidirectional bus sharing and signal isolation.
What package is the SN74ACT241NSR available in?
The SN74ACT241NSR is available in a 20-pin small-outline IC (SOIC) package in narrow-body format, supplied in tape-and-reel (NSR suffix) for surface-mount automated assembly on high-volume PCB production lines.
What applications is the SN74ACT241NSR designed for?
It is designed for bus buffering, signal isolation, and 3-state bus multiplexing in microprocessor systems, memory interfaces, and industrial PLCs where high drive strength and fast propagation delay from the ACT logic family are required.
