74AHC240PW-Q100J

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHC240PW-Q100J is an octal buffer and line driver manufactured by Nexperia, a brand under NXP USA Inc. It belongs to the AHC logic series and features non-inverting outputs with three-state capability. The device operates within a supply voltage range of 2 V to 5.5 V and supports output drive currents of 8 mA at both high and low logic levels. It is housed in a 20-TSSOP package and is qualified to the AEC-Q100 standard for Grade 1 automotive applications, ensuring reliability across an operating temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent non-inverting buffers within a single integrated circuit.
• Three-state output architecture allowing effective bus isolation when the output enable input is activated.
• Automotive qualification compliant with AEC-Q100 standards for robust performance in vehicle environments.
• Wide supply voltage compatibility supporting operation from 2 V up to 5.5 V.

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive data bus systems requiring high-speed signal buffering
• Microcontroller I/O expansion and port driving
• Memory interface circuits utilizing bidirectional data lines

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by Nexperia under license or acquisition from NXP. Confirm the specific suffix matches the required automotive grade and packaging type. Ensure the ordering code aligns with the exact pinout and electrical specifications defined in the official datasheet to prevent integration errors.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for automotive or industrial designs. It serves as a suitable alternative to legacy HC series parts where higher speed and lower power consumption are necessary. Consider the TSSOP-20 footprint constraints and verify that the 8 mA drive current meets the load requirements of the connected circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is a member of the 74AHC family, which offers significantly faster switching speeds compared to standard 74HC devices while maintaining similar pinouts. The Q100 suffix indicates compliance with automotive reliability standards, distinguishing it from commercial-grade variants. It is functionally compatible with other 74AHC logic families, facilitating mixed-logic system design.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the 74AHC240PW from Nexperia without the Q100 suffix for non-automotive use, or equivalent octal buffers from manufacturers like Texas Instruments and onsemi. Verify that any replacement maintains the same 20-TSSOP package and three-state functionality.
