CY74FCT244ATPC

Overview

The CY74FCT244ATPC is an octal buffer and line driver with three-state outputs manufactured by Texas Instruments. It belongs to the FCT logic series and utilizes CMOS technology. The device operates within a supply voltage range of 4.75 V to 5.25 V. It features a propagation delay of 4.1 ns at 5 V. The component supports TTL input and output levels. It provides a high-level output current of -32 mA and a low-level output current of 64 mA. The static current is specified at 200 nA, with a working power supply current of 3.3 mA. It is housed in a SOIC-20 package and functions as a non-inverting buffer.

Feature Summary

• Octal configuration providing eight independent buffering channels
• Three-state outputs for effective bus line management
• High drive capability suitable for demanding load conditions

Applications

• Clock distribution networks
• Memory address drivers
• Signal buffering between digital subsystems

Procurement Notes

Verify the specific suffix 'ATPC' against the manufacturer's official datasheet to confirm the exact package type and temperature rating. Ensure the ordering information matches the required pinout and electrical specifications for the target application design.

Selection Notes

Select this component when an octal buffer with high drive strength is required. The FCT series offers speed comparable to LS logic with CMOS power consumption. Verify that the system voltage aligns with the 4.75 V to 5.25 V operating range before integration.

Part Context

This part is part of the CY74FCT244T family of octal buffers. It serves as a standard interface solution for connecting microprocessors to memory or peripheral devices. The device ensures signal integrity through its three-state output capability and robust drive characteristics.

Replacement Considerations

Check for direct equivalents such as the CY74FCT244TSOC for surface mount variants. Verify compatibility with other FCT-series buffers like the CY74FCT541 if bidirectional transfer is needed.
