74AHC240D,118

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHC240D,118 is an octal buffer and line driver featuring inverting logic and three-state outputs. It operates within a supply voltage range of 2.0 V to 5.5 V. The device provides balanced propagation delays with typical values ranging from 2.8 ns to 7.5 ns depending on load conditions. It includes two independent output enable inputs (1OE and 2OE) for controlling four outputs each. Inputs are over-voltage tolerant, allowing operation in mixed-voltage environments.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features Schmitt-trigger action on all inputs for improved noise immunity
• Provides high-impedance OFF-state via active LOW output enable signals
• Supports mixed-voltage translation through over-voltage tolerant inputs

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address and data bus drivers
• Clock distribution buffers
• Line termination circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '118' against current manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or NXP Semiconductors sales offices prior to procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring eight-channel signal inversion with tri-state control. Ensure the operating temperature range meets application requirements, as the SO20 package supports -40 °C to +125 °C. Verify that input voltage levels remain within the specified limits relative to the supply voltage.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC family of high-speed CMOS logic devices manufactured by NXP Semiconductors. It serves as an octal version of the standard buffer series, offering increased channel density compared to single or dual buffer configurations while maintaining low power consumption characteristics typical of the AHC technology node.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT240D,118 is a compatible variant within the same product family. It shares identical pinout and functionality but requires TTL-compatible input voltage levels rather than CMOS levels.
