CD74FCT244SM96

Overview

The CD74FCT244SM96 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 corresponding outputs with three-state capability. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical specifications include a high-level output current of -32 mA and a low-level output current of 64 mA. Static current consumption is rated at 200 nA, while operating power supply current reaches 3.3 mA. Propagation delay is specified at 4.1 ns at 5 V. The component is housed in a SOIC-20 package and supports surface-mount installation.

Feature Summary

• Provides octal buffering and line driving functions for digital signal transmission
• Features three-state outputs to facilitate bus-oriented systems
• Utilizes BiCMOS technology for high-speed performance

Applications

• Bus-oriented memory and address drivers
• Clock drivers
• Buffering for I/O circuits

Procurement Notes

Verify the specific suffix SM96 against official datasheets to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for SOIC-20 packages. Confirm RoHS compliance status through manufacturer documentation before procurement.

Selection Notes

Select this component when designing systems requiring high-speed data transfer with low propagation delay. The FCT series offers CMOS compatibility with TTL drive levels. Consider the three-state output feature for managing multiple devices on shared buses. Verify thermal requirements for the SOIC-20 package in enclosed environments.

Part Context

This part belongs to the CD74FCT244 family of octal buffers. Similar variants include CY74FCT244CTSOC and CD74FCT244M96G4. These components share core logical functionality but may differ in packaging, temperature ranges, or manufacturing revisions. The FCT series bridges the speed gap between standard TTL and CMOS technologies.

Replacement Considerations

Check for direct substitutes like CD74FCT244M96G4. Verify pinout compatibility and electrical parameters such as output current capabilities. Ensure the replacement maintains the same three-state control logic and voltage operating range.
