MC74VHC240DTR2G

Overview

The MC74VHC240DTR2G is an octal inverting buffer and line driver manufactured by onsemi, belonging to the VHC logic series. It operates within a supply voltage range of 2 V to 5.5 V and features three-state outputs for bus-oriented applications. The device utilizes high-performance silicon-gate CMOS technology to achieve low power consumption and high noise immunity. Key electrical parameters include a propagation delay of 11 ns, output currents of ±8 mA, and a maximum power dissipation of 450 mW. It is housed in a 20-TSSOP surface-mount package with an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent inverting buffers or line drivers within a single integrated circuit.
• Three-state output capability designed specifically for efficient bus-driven architectures and signal routing.
• High-speed performance characterized by a propagation delay of 11 ns suitable for demanding digital interfaces.
• Robust input protection mechanisms integrated to withstand electrostatic discharge events.

Applications

• Bus-oriented memory and address drivers
• Clock buffering and distribution circuits
• Multiplexer control logic

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into manufacturing processes. Cross-reference the datasheet revision history to validate current technical parameters and pinout configurations.

Selection Notes

Select this component when designing systems requiring octal signal inversion with bus isolation capabilities. Ensure the operating voltage aligns with the 2 V to 5.5 V specification and that the TSSOP-20 package fits the board layout constraints. Consider the 11 ns propagation delay relative to system timing requirements and verify thermal management for the specified power dissipation limits.

Part Context

This part belongs to the MC74VHC240 family of octal buffers and line drivers produced by onsemi. It shares functional similarities with other devices in the VHC series but is distinguished by its specific voltage range and package type. The DTR2G suffix indicates the surface-mount TSSOP-20 packaging and lead-free construction compliant with environmental standards.
