74LVC1G240DCKRG4

Overview

The SN74LVC1G240DCKRG4 is a single buffer and line driver from the Texas Instruments LVC logic family. It features an inverting configuration with three-state outputs housed in a SC-70-5 package. The device operates within a supply voltage range of 1.65 V to 5.5 V, supporting high drive capabilities with output currents of -32 mA at high levels and 32 mA at low levels. It exhibits a propagation delay of 4.2 ns at 5 V and maintains a static current of 10 uA. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides single-channel buffering with inverting logic polarity for signal inversion applications.
• Features three-state outputs allowing effective bus driving and isolation in multi-driver systems.
• Supports wide supply voltage operation from 1.65 V to 5.5 V for compatibility with various logic families.

Applications

• Bus-oriented communications
• Clock distribution and buffering
• Memory data bus drivers

Procurement Notes

Verify the specific ordering suffix 'RG4' against the manufacturer's official documentation to confirm RoHS compliance status and tape-and-reel packaging specifications. Ensure the SC-70-5 footprint matches the target PCB design constraints. Cross-reference the full part number SN74LVC1G240DCKRG4 with the latest datasheet revision to validate electrical parameters and thermal characteristics before finalizing procurement.

Selection Notes

Select this component when a compact, single-channel inverting buffer with three-state capability is required. The LVC series offers a balance of speed and power consumption suitable for general-purpose digital logic applications. Consider the SC-70-5 package size for space-constrained designs. Verify that the 1.65 V to 5.5 V operating range aligns with the system's power supply rails and that the 32 mA drive current meets the load requirements.

Part Context

This device belongs to the SN74LVC1G240 series of single buffer/drivers with three-state outputs. It is part of the broader LVC (Low Voltage CMOS) logic family, designed for low-power applications requiring high switching speeds. The DCKR variant indicates the SC-70-5 surface-mount package, while the RG4 suffix typically denotes environmental compliance and reel packaging options defined by the manufacturer.

Replacement Considerations

Direct functional substitutes within the same family include SN74LVC1G240DCKR. For alternative packages, SN74LVC1G240YZPR (DSBGA-5) offers similar electrical performance in a different footprint. Verify pinout compatibility and electrical specifications before substituting.
