74AHC240PW,112

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHC240PW,112 is an octal buffer and line driver manufactured by NXP USA Inc. It features inverting logic with three-state outputs housed in a TSSOP20 package (SOT360-1). The device operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. Inputs are over-voltage tolerant, allowing operation in mixed-voltage environments. The component includes two output enable inputs (1OE and 2OE), each controlling four outputs.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the procurement channel sources genuine NXP Semiconductors products to ensure compliance with specified electrical characteristics. Check for RoHS3 compliance status if environmental regulations apply to the final assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with three-state capability is required. Ensure the system design accommodates the 2.0 V to 5.5 V supply voltage range. Verify that the TSSOP20 footprint aligns with the PCB layout constraints and thermal management requirements for the intended operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC series of high-speed CMOS logic devices. It serves as a digital logic interface component designed for general-purpose applications requiring signal buffering and level shifting. The device is distinct from the 74AHCT variant, which utilizes TTL-compatible input thresholds instead of CMOS levels.
