MC74AC240DW

Overview

The MC74AC240DW is an octal buffer and line driver manufactured by onsemi, belonging to the 74AC logic series. It features eight inverting outputs with three-state capability, allowing for effective bus-oriented communications. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a high-level output current of -24 mA and a low-level output current of 24 mA. Static current is specified at 8 µA, while operating supply current reaches 80 µA. The component is housed in a SOIC-20 package and supports a minimum operating temperature of -40°C.

Feature Summary

Provides octal buffering with three-state output control for bus systems
Features inverting logic polarity for signal direction management
Supports symmetrical output impedance for transmission line driving

Applications

Bus-oriented communications systems
Clock distribution circuits
Memory data register interfacing

Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 surface-mount package configuration required for your design. Confirm RoHS compliance status through official datasheets, as manufacturing processes may vary. Check for obsolescence notices from onsemi, as this component family has faced lifecycle changes. Ensure the ordering part number matches the exact package and tape/reel specifications needed for your assembly process.

Selection Notes

Select this component when designing systems requiring high-speed octal buffering with three-state outputs. The 74AC series offers faster propagation delays compared to standard 74LS or 74HC families. Consider the 2 V to 6 V operating range for compatibility with various logic levels. Evaluate the 24 mA drive capability against load requirements to ensure signal integrity across the bus structure.

Part Context

This device is part of the broader 74AC240 family of octal buffers. Variants such as MC74AC240N (PDIP) and MC74AC240DWR2G (tape & reel) share identical logical functions but differ in packaging and shipping formats. The MC74AC240DW specifically denotes the plastic small-outline integrated circuit package suitable for surface-mount technology applications.
