CY74FCT244TSOC

Overview

The CY74FCT244TSOC is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting input lines and three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 4.1 ns at 5 V, high-level output current of -32 mA, and low-level output current of 64 mA. Static current is specified at 200 nA, with a maximum operating temperature of +85°C.

Feature Summary

• Provides buffering and line driving capabilities for digital signals
• Features three-state outputs for bus-oriented applications
• Supports non-inverting signal transmission

Applications

• Bus-oriented systems requiring signal buffering
• Memory address drivers
• Clock drivers

Procurement Notes

Verify the specific suffix 'TSOC' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the order quantity aligns with standard tube packaging requirements defined by Texas Instruments. Confirm RoHS compliance status through the latest environmental documentation provided by the supplier before finalizing procurement.

Selection Notes

Select this component when designing circuits that require octal buffering with three-state control. Verify that the system voltage falls strictly between 4.75 V and 5.25 V. Consider the 4.1 ns propagation delay for timing constraints. Ensure the thermal environment remains within the -40°C to +85°C operational range for reliable performance.

Part Context

This part belongs to the CY74FCT244T family of octal buffers and line drivers. It shares functional similarities with other FCT series devices but is distinct from variants like the CY74FCT245CTSOC, which functions as a transceiver rather than a unidirectional buffer. The SOIC-20 package distinguishes it from surface-mount tape-and-reel or leaded alternatives.
