CY74FCT2541ATSOC

Overview

The CY74FCT2541ATSOC is an octal line driver and MOS driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting inputs driving three-state outputs within a 20-pin SOIC package. The device operates on a supply voltage ranging from 4.75 V to 5.25 V. Key electrical parameters include a high-level output current of -15 mA and a low-level output current of 12 mA. Static current consumption is specified at 200 nA, with a typical propagation delay of 4.1 ns at 5 V. The component supports surface mount installation and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides unidirectional buffering for eight input lines with independent control via dual output enable pins.
• Features three-state outputs designed to drive MOS loads and standard bus structures effectively.
• Utilizes CMOS technology to achieve low static power consumption while maintaining fast signal transition speeds.

Applications

• Bus-oriented memory and command decoding systems
• Clock drivers and buffer circuits
• MOS memory address and data drivers

Procurement Notes

Verify the specific suffix 'A' indicates the industrial temperature grade (-40°C to +85°C) compared to commercial variants. Confirm the 'SOC' designation corresponds to the 20-SOIC package type. Ensure compatibility with 5V logic levels as defined in the official datasheet specifications before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high-speed, unidirectional data transfer with multiple load capabilities. The FCT series offers performance comparable to LS-TTL but with CMOS power advantages. Consider the 20-SOIC footprint constraints and verify that the required drive strength meets the specific capacitive load requirements of the target application circuit.

Part Context

This part belongs to the CY74FCT2541T family of octal buffers and line drivers. It serves as a specialized interface solution within Texas Instruments' broader portfolio of high-speed logic components. The device is engineered to bridge microprocessor buses with peripheral devices, ensuring signal integrity across digital communication pathways in complex electronic assemblies.

Replacement Considerations

The CY74FCT2541ATQCT is a verified alternative offering identical logical functionality in a QSOP-20 package. Cross-reference pinouts and electrical characteristics to ensure mechanical fit and performance equivalence during design updates or supply chain adjustments.
