CY74FCT244TQCT

Overview

The CY74FCT244TQCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting inputs and outputs with three-state capability, housed in a QSOP-20 surface-mount 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 4.6 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-channel buffering with tri-state output control for bus interfacing
• Utilizes CMOS technology for low static power consumption
• Supports TTL-compatible input and output voltage levels

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Multiple bus transceivers

Procurement Notes

Verify the specific suffix 'QCT' against the manufacturer's official datasheet to confirm the exact package type (QSOP-20) and tape-and-reel packaging configuration. Ensure compatibility with required moisture sensitivity levels and RoHS compliance standards before procurement.

Selection Notes

Select this component when an octal buffer with three-state outputs is required for 5V logic systems. Consider the 4.6 ns propagation delay and drive strength (-32 mA/64 mA) relative to load capacitance requirements. Verify that the QSOP-20 package fits the PCB footprint constraints.

Part Context

This part belongs to the CY74FCT244T family of octal buffers. It serves as a standard interface solution for connecting microprocessors or controllers to peripheral devices on a shared bus architecture, ensuring signal integrity through buffered driving capabilities.
