74HC240PW,112

Overview

The Nexperia 74HC240PW,112 is an octal buffer and line driver featuring inverting logic with three-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device utilizes a TSSOP20 package (SOT360-1) containing 20 leads with a body width of 4.4 mm. It includes two output enable inputs (1OE and 2OE), each controlling four outputs, and incorporates input clamp diodes for interfacing with voltages exceeding VCC.

Feature Summary

• Features inverting three-state outputs controlled by separate active LOW enable signals.
• Includes input clamp diodes allowing interface to voltages higher than the supply voltage using current limiting resistors.
• Provides high noise immunity and low power CMOS dissipation characteristics.

Applications

• Bus-oriented communications systems
• Clock drivers
• Memory address decoding

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP20 package variant when sourcing. Confirm that the procurement channel provides the official Nexperia datasheet Rev. 7 dated 5 August 2024 to ensure alignment with the latest ESD protection specifications and static characteristics. Ensure design compatibility with the specified operating temperature range.

Selection Notes

Select this component for applications requiring octal buffering with inverting functionality and three-state control. The wide supply voltage range accommodates various logic families. Verify that the required propagation delay and output drive capabilities meet system timing constraints under the intended load capacitance and supply voltage conditions.

Part Context

This part belongs to the 74HC/HCT logic family, designed for general-purpose digital applications. The PW suffix indicates the plastic thin shrink small outline package. It serves as a standard solution for driving bus lines and managing signal integrity in complex digital layouts where multiple devices share communication pathways.

Replacement Considerations

The 74HCT240PW,112 offers identical pinout and functionality but requires a minimum supply voltage of 4.5 V due to TTL input levels. Other package variants such as 74HC240D or 74HC240BQ provide alternative form factors while maintaining electrical equivalence.
