SN74AUCH240RGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUCH240RGYR is an octal buffer and driver with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 0.8 V to 2.7 V, optimized for 1.65-V to 1.95-V applications. The device features I/O tolerance up to 3.6 V, supporting mixed-mode signal environments. Electrical characteristics include a maximum propagation delay of 1.7 ns at 1.8 V and output drive capabilities of ±8 mA at the same voltage. It incorporates active bus-hold circuitry on data inputs and supports partial-power-down mode via Ioff functionality.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Optimized for low-voltage operation down to 0.8 V while maintaining 3.6-V I/O tolerance for mixed-signal compatibility
• Integrated active bus-hold circuitry maintains valid logic states on undriven inputs without external resistors
• Ioff circuitry disables outputs during power-down to prevent damaging backflow current in partial-power-down scenarios

Buffers, Drivers, Receivers, Transceivers Applications

• Three-state memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel quantity. Confirm RoHS compliance status and moisture sensitivity level requirements against your manufacturing process specifications. Ensure the operating temperature range aligns with your system's thermal environment constraints before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-density octal buffering with sub-1-V operability. It is suitable for applications needing 3.6-V tolerant inputs to interface with higher voltage logic levels. Consider its low static power consumption and fast switching speeds for performance-critical bus architectures.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AUCH series of ultra-low-voltage CMOS logic devices. It provides eight non-inverting buffers or drivers organized as two independent 4-bit sections. Each section includes a separate output-enable control input to manage data flow direction and high-impedance states efficiently.
