MC74LVX244DW

Overview

The MC74LVX244DW is an octal buffer and line driver manufactured by onsemi, belonging to the LVX logic series. It features eight non-inverting inputs and outputs housed in a SOIC-20 surface-mount package. The device operates within a supply voltage range of 2 V to 3.6 V. Key electrical parameters include a maximum high-level output current of -4 mA and a low-level output current of 4 mA. Static current is specified at 4 uA, with a maximum operating power supply current of 40 uA. Propagation delay is 14.9 ns at 2.7 V and 10.6 ns at 3.3 V. The component supports a power dissipation of 180 mW and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides octal buffering with three-state output capability for efficient bus management.
• Supports low-voltage operation suitable for systems requiring 2 V to 3.6 V power supplies.
• Features non-inverting signal transmission with defined propagation delays.

Applications

• Memory mapping control circuits
• Clock drivers
• Bus-oriented transmissions

Procurement Notes

Verify the specific suffix 'DW' against the manufacturer's official documentation to confirm the SOIC-20 package variant and tape-and-reel or tube packaging configuration. Ensure compatibility with the required operating temperature range and voltage specifications before integration. Cross-reference the RoHS compliance status directly with the latest datasheet revision to meet environmental regulations.

Selection Notes

Select this component when designing systems requiring octal buffering with low static power consumption and operation below 3.6 V. Compare propagation delays against system timing requirements, noting variations between 2.7 V and 3.3 V supply conditions. Consider the SOIC-20 footprint constraints and thermal dissipation limits relative to the PCB layout and ambient operating conditions.

Part Context

This part belongs to the LVX family of low-voltage CMOS logic devices from onsemi. It serves as an octal buffer and line driver, distinct from higher-voltage AC or LCX series counterparts. The LVX series is characterized by its ability to operate at lower supply voltages while maintaining compatible interface levels for various digital applications.

Replacement Considerations

Check for direct equivalents such as the 74LVX244MX from the same manufacturer. Verify pinout compatibility and electrical characteristics against other octal buffer variants like the MC74LCX244DWG, ensuring voltage tolerance and speed requirements are met.
