74LVC827ADB,112

Overview

The Nexperia 74LVC827ADB,112 is a 10-bit buffer and line driver featuring 3-state outputs controlled by OE1 and OE2 pins. It operates within a supply voltage range of 1.2 V to 3.6 V, with functional operation starting at 1.65 V. The device supports inputs driven from 3.3 V or 5 V devices, allowing use as a translator in mixed-voltage environments. When disabled, up to 5.5 V can be applied to the outputs. It complies with JEDEC standards for various voltage ranges and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Propagation delay ranges from 1.0 ns to 15.5 ns depending on voltage.

Feature Summary

• Provides 10-bit buffering with 3-state output capability controlled by active LOW enable pins.
• Features 5 V tolerant inputs and outputs, enabling direct interfacing with 5 V logic systems.
• Supports mixed 3.3 V and 5 V applications by accepting inputs from either voltage level.
• Includes robust ESD protection compliant with HBM and CDM standards.

Applications

• Translating signals between mixed 3.3 V and 5 V logic environments
• Buffering data lines in high-density digital systems
• Line driving applications requiring 3-state isolation

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the SSOP-24 package (SOT340-1) as defined in the official datasheet. Confirm that the required operating temperature range of -40 °C to +125 °C aligns with your system specifications. Ensure input voltage levels do not exceed the absolute maximum ratings to prevent damage. Check for any recent product change notices regarding assembly locations or material updates.

Selection Notes

Select this component when a 10-bit wide bus requires buffering with tri-state control. It is suitable for designs needing compatibility with both 3.3 V and 5 V logic families without additional level shifting circuitry. Consider the SSOP-24 package constraints if space is limited. Verify that the propagation delay characteristics meet the timing requirements of your specific clock speeds.

Part Context

This part belongs to the 74LVC827A family of 10-bit buffers/line drivers. The 'ADB' suffix specifically denotes the SSOP24 plastic shrink small outline package with a body width of 5.3 mm. Other variants in the family include SO24 and TSSOP24 packages. The device is designed for low-power CMOS applications and offers direct interface capabilities with TTL levels.

Replacement Considerations

Check for other package variants of the same logical function, such as 74LVC827AD (SO24) or 74LVC827APW (TSSOP24), if pin compatibility allows. Ensure any substitute maintains the 10-bit width and 3-state output configuration. Verify that the replacement also supports the required 5 V tolerance and supply voltage range.
