Frequently Asked Questions
How many bits does the CY74FCT2541TSOCTE4 buffer, and in which direction?
The CY74FCT2541TSOCTE4 is a unidirectional 8-bit bus buffer. All eight data paths drive in the same direction from inputs to outputs, making it ideal for applications where data flow is one-way, such as address bus buffering or output port expansion in microprocessor-based systems.
How does the dual output enable work on the CY74FCT2541TSOCTE4?
The device features two independent active-low output enable (OE) pins. Both must be asserted low simultaneously to enable the outputs; if either is deasserted high, all eight outputs go into a high-impedance tri-state condition. This dual-enable architecture adds flexibility for bus arbitration and multi-master system designs.
What logic family does the CY74FCT2541TSOCTE4 belong to?
The CY74FCT2541TSOCTE4 belongs to the FCT (Fast CMOS Technology) logic family, which combines the low power of CMOS with propagation delay and drive strength comparable to bipolar FCT/ABT logic. It is compatible with standard TTL input levels and is well-suited for high-speed bus interface applications at 5V.
What is the maximum load capacitance and output current of the CY74FCT2541TSOCTE4?
The device is rated for a load capacitance of 50pF and a maximum low-level output current (I_OL) of 12mA. These parameters ensure reliable signal integrity when driving moderately loaded PCB bus traces in backplane, memory, and embedded processor interface applications.
What package is the CY74FCT2541TSOCTE4 available in?
The CY74FCT2541TSOCTE4 comes in a 20-pin SOIC (Small Outline IC) surface-mount package. This widely available package provides a good balance of compact PCB footprint and ease of hand-soldering or automated SMT assembly, and it is compatible with standard 20-pin SOIC footprints found on most PCB design libraries.
