SN74AUC2G240DCTR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC2G240DCTR is a dual buffer and line driver from the Texas Instruments AUC logic family. It features two independent channels with inverting logic and three-state outputs. The device operates within a supply voltage range of 0.8 V to 2.7 V. Key electrical parameters include a propagation delay of 1.5 ns at 2.7 V, output drive currents of ±9 mA, and low static current consumption. It is housed in an SM-8 (SC-70) package and supports operation temperatures from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• High-speed performance with 1.5 ns propagation delay

Buffers, Drivers, Receivers, Transceivers Applications

• Mobile phone and handheld equipment internal connections
• Clock buffering and distribution circuits
• Memory and timing signal drivers
• Consumer electronics data line drivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DCTR indicates the cut-tape or reel packaging configuration upon ordering. Confirm that the 0.8V to 2.7V operating range aligns with the target system's power rails. Ensure the SM-8 package footprint matches the PCB design constraints. Check for RoHS compliance status as required by regional regulations.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when low voltage operation below 3.3V is required alongside high-speed switching capabilities. The AUC series offers superior speed-to-power efficiency compared to older LVC or LV families. Consider the dual-channel configuration if space is limited and multiple inversion stages are needed. Verify input/output voltage compatibility with the connected logic levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AUC2G240 series, which represents Texas Instruments' advanced ultra-low voltage CMOS technology. The series is designed for portable applications requiring minimal power usage without sacrificing speed. It serves as a compact alternative to octal buffers, offering functional equivalence in a significantly smaller surface-mount package.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74AUP2G240DCUR is a recommended replacement with similar functionality but a wider voltage range up to 3.6V. For pin-compatible alternatives, check the SN74AUC2G240DCUR variant which shares the same package type.
