74LVTH244MSAX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74LVTH244MSAX is a low-voltage octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.7V to 3.6V, with input voltages supporting up to 5.5V for TTL interface compatibility. The device utilizes advanced BiCMOS technology to achieve high-speed operation while maintaining low power dissipation. Key electrical characteristics include propagation delays ranging from 1.1ns to 4.2ns depending on load conditions, and output drive capabilities sourcing -32mA and sinking 64mA. The 'X' suffix indicates tape and reel packaging.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs
• Power Up/Down high impedance provides glitch-free bus loading
• Live insertion/extraction permitted
• Functionally compatible with the 74 series 244

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• Clock drivers
• Bus oriented transmitters or receivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'X' corresponds to tape and reel packaging as specified in the datasheet. Confirm the specific package variant (e.g., MSA for SSOP) matches the required footprint. Ensure the component meets lead-free standards per JEDEC J-STD-020B. Check for any obsolescence notices or lifecycle changes from the manufacturer.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with bushold functionality is required for 3.3V systems interfacing with 5V environments. Consider the 74LVT244 if bushhold features are not needed. Evaluate the trade-off between the higher drive current of the LVT series and the speed/power benefits of LVX series alternatives based on specific circuit requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LVT/74LVTH logic family, designed for low-voltage applications. It is functionally similar to the 74FCT244 but optimized for lower power consumption. The device is manufactured using BiCMOS technology to provide performance comparable to 5V ABT devices while operating at reduced voltages.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74LVT244 is a functional substitute lacking the bushold feature. Other manufacturers may offer equivalents such as the SN74LVT244 or MC74LVTH244. Verify pinout compatibility and electrical specifications before substitution.
