CY74FCT244DTSOC

Overview

The CY74FCT244DTSOC is an octal buffer and line driver from the Texas Instruments FCT logic family, housed in a 20-pin SSOP package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. The device features three-state outputs with a maximum low-level output current of 64 mA and a maximum high-level output current of -32 mA. Propagation delay is specified at 4.6 ns under a 50 pF load at 5 V. It functions reliably across an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Provides eight non-inverting buffered channels for signal driving applications
• Features three-state outputs to facilitate bus-oriented architectures
• Supports TTL-compatible input and output voltage levels

Applications

• Bus-oriented system architectures requiring signal buffering
• Memory address drivers for data buses
• Clock distribution circuits

Procurement Notes

Verify the specific suffix 'DTSO' against the manufacturer's official datasheet to confirm the exact tape-and-reel quantity and packaging configuration. Ensure the order matches the required operating temperature range and package dimensions. Cross-reference the component marking with the latest production notices to avoid obsolete or discontinued variants.

Selection Notes

Select this component when an octal buffer with three-state capability is required for 5V logic systems. It is suitable for designs needing high drive strength and fast switching speeds. Consider the SSOP package constraints regarding thermal dissipation and board space. Verify that the application does not require bidirectional data flow, as this part is unidirectional.

Part Context

This component belongs to the Texas Instruments 74FCT series, which utilizes BiCMOS technology to combine the speed of bipolar devices with the low power consumption of CMOS. The FCT family is designed for high-performance digital applications, offering improved noise immunity and faster propagation delays compared to standard 74LS logic families.
