MC74LVX240DTR2G

Overview

The MC74LVX240DTR2G is an octal buffer and line driver manufactured by onsemi, belonging to the LVX logic series. It features eight inverting outputs with three-state capability, housed in a TSSOP-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 low-level output current of 4 mA and a high-level output current of -4 mA. Propagation delay is specified at 14.9 ns at 2.7 V and 10.6 ns at 3.3 V. The component supports a wide operating temperature range from -40 °C to +85 °C.

Feature Summary

• Provides octal buffering and line driving capabilities with inverting logic polarity.
• Integrates three-state outputs to facilitate bus-oriented communication systems.
• Operates effectively across a low-voltage power supply range of 2 V to 3.6 V.

Applications

• Bus-oriented systems requiring signal buffering
• Memory and command addressing applications
• Clock drivers for timing distribution

Procurement Notes

Verify that the specific part number matches the required LVX series specifications, as similar suffixes may indicate different packaging or voltage tolerances. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the TSSOP-20 footprint aligns with the design layout. Cross-reference datasheet revisions to confirm parameter consistency for critical timing requirements.

Selection Notes

Select this component when designing circuits requiring octal buffering with three-state control within the 2 V to 3.6 V operational window. The LVX series offers a balance of speed and low power consumption suitable for portable electronics. Compare propagation delays against system clock speeds to ensure signal integrity. Verify that the 4 mA drive current meets the load requirements of the destination inputs.

Part Context

This component is part of the MC74LVX family of CMOS logic integrated circuits produced by onsemi. The LVX series is designed for low-voltage applications, offering performance comparable to older standards while consuming less power. It shares functional similarities with other octal buffers like the MC74LVX244, which provides non-inverting outputs instead of inverting ones.

Replacement Considerations

MC74LVX244DTR2G serves as a direct functional substitute if non-inverting output polarity is acceptable. Other compatible options within the same voltage and package constraints should be verified against specific timing and drive current requirements before substitution.
