CY74FCT244ATSOCT

Overview

The CY74FCT244ATSOCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features non-inverting polarity and three-state outputs within a 20-pin SOIC package. The device operates on 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 eight non-inverting signal paths for buffering or driving loads
• Integrates three-state output capability for bus-oriented applications
• Utilizes CMOS technology within the FCT logic family for performance

Applications

• Bus-oriented memory and address drivers
• Clock buffers and drivers
• Multiplexer input and output switches

Procurement Notes

Verify the specific suffix 'ATSOCT' against the official datasheet to confirm the exact tape-and-reel packaging quantity and temperature grade. Ensure the ordering part number matches the required package style and lead-free status. Cross-reference the manufacturer's latest documentation for any pinout or electrical specification updates prior to final procurement.

Selection Notes

Select this component when an octal buffer with three-state control is required in a surface-mount SOIC-20 package. It is suitable for designs needing high drive strength (64 mA sink) and fast switching speeds (4.1 ns delay). Verify that the system power supply remains strictly within the 4.75 V to 5.25 V range to ensure proper operation.

Part Context

This part is part of the CY74FCT244T series, which includes variants with different packaging options such as tubes or reels. The 'A' typically denotes a specific speed grade or manufacturing lot code, while 'TSOC' indicates the SOIC-20 package type. Other related parts in the family may offer different pin configurations or additional control inputs.

Replacement Considerations

Direct replacements include other CY74FCT244 variants with compatible packaging. Check for equivalent parts from other manufacturers like ON Semiconductor or Renesas that match the FCT specifications, SOIC-20 footprint, and electrical characteristics.
