Frequently Asked Questions
What load capacitance can the SN74HC241PWG4 drive on each output channel?
Each output channel of the SN74HC241PWG4 can drive up to 50 pF of load capacitance, making it suitable for driving long PCB traces or multiple parallel loads on an 8-bit bus without signal integrity degradation.
How does the SN74HC241PWG4 manage bus contention in shared data-bus designs?
The SN74HC241PWG4 uses dual enable inputs, one active LOW and one active HIGH, allowing system logic to tri-state all 8 outputs simultaneously. When disabled, outputs present high impedance, preventing bus contention when multiple drivers are connected to the same 8-bit data or address bus.
When is the SN74HC241PWG4 preferred over the SN74HC244 in a design?
The SN74HC241PWG4 is preferred when separate enable polarities are needed, since it provides both an active-LOW and an active-HIGH enable pin. The SN74HC244 uses only active-LOW enables, so the SN74HC241 offers greater flexibility in systems where control signals have mixed polarities across 8 channels.
What is the maximum output sink current per channel for the SN74HC241PWG4?
The SN74HC241PWG4 has a maximum output low current (I_OL) of 6 mA per channel. This current handling is sufficient for typical TTL-compatible loads and standard CMOS bus interconnects operating at 3.3V or 5V supply rails.
