TC74LVX244FTFTELM

Overview

The TC74LVX244FT is an octal bus buffer manufactured by Toshiba Semiconductor and Storage. It features non-inverted, three-state outputs and operates within a supply voltage range of 2.0 V to 3.6 V. The device supports inputs up to 5.5 V regardless of the supply voltage. It utilizes a 20-TSSOP package with a width of 4.40 mm. Typical propagation delay is 4.7 ns at 3.3 V. Maximum quiescent current is 4 μA at 25°C.

Feature Summary

• High-speed CMOS technology for low power dissipation
• Input protection circuit allowing 0 to 5.5 V tolerance
• Pin and function compatible with 74HC240/244

Applications

• 3-state memory address drivers
• Interface between 5V and 3V systems
• Battery backup system interfacing

Procurement Notes

Verify the exact ordering suffix against the manufacturer's datasheet to confirm the specific package type (F or FT) and tape-and-reel specifications. Confirm RoHS compliance status directly with the supplier as environmental classifications can vary by production batch. Ensure the component matches the required operating temperature range of -40°C to 85°C for your specific application environment.

Selection Notes

Select this component when an octal buffer with non-inverted logic and three-state control is required. It is suitable for applications needing high noise immunity and balanced propagation delays. Consider the 5.5 V input tolerance if interfacing with higher voltage logic levels while maintaining a lower core supply voltage.

Part Context

This part belongs to the TC74LVX series of high-speed CMOS digital integrated circuits. It is functionally similar to the TC74LVX240 but provides non-inverted outputs instead of inverted ones. Both variants share identical pinouts and electrical characteristics except for the logic inversion state.

Replacement Considerations

Direct substitutes include the TC74LVX240 for inverted output requirements. Other compatible devices in the same family may be considered if pinout compatibility is maintained.

FAQ

What is the maximum input voltage supported by the TC74LVX244FT?

The device supports DC input voltages from 0 V to 5.5 V, independent of the supply voltage.

Does the TC74LVX244FT provide power-down protection?

Yes, the device includes power-down protection on all inputs to prevent excessive current draw during power-off states.
