Overview
The Texas Instruments 74AC11810D is a CMOS logic integrated circuit containing four independent XNOR gates. It operates within a supply voltage range of 1.5 V to 5.5 V, providing balanced noise immunity at 30% of the supply voltage. The device utilizes a 16-pin Small Outline Integrated Circuit (SOIC) package with surface-mount technology. It supports high-speed operation characteristic of the AC series, suitable for general-purpose digital applications requiring exclusive-NOR logic functions.
Feature Summary
- Contains four independent two-input XNOR logic gates
- Operates across a wide 1.5 V to 5.5 V supply voltage range
- Provides balanced noise immunity relative to supply voltage
- Available in a standard 16-pin SOIC surface-mount package
Applications
- Digital logic circuits requiring exclusive-NOR functionality
- Data comparison and parity checking systems
- General-purpose digital signal processing interfaces
Procurement Notes
Verify the specific suffix 'D' corresponds to the 16-pin SOIC package variant when sourcing. Confirm that the component meets the required operating temperature range for your application environment. Ensure compatibility with your system's voltage levels, as the device supports both low-voltage and standard 5 V logic families. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.
Selection Notes
Select this component when a compact solution for multiple XNOR operations is needed within a single package. The AC series offers a balance between speed and power consumption compared to older HC or HCT variants. Consider the 16-pin SOIC footprint for PCB layout constraints. Verify input voltage thresholds align with your driving logic family to ensure reliable switching performance across the full operating temperature range.
Part Context
This part belongs to the Texas Instruments 74AC series of high-speed CMOS logic devices. The 74AC family is designed to replace earlier 74HC and 74HCT components while offering faster propagation delays. The 11810 designation specifically identifies the quad XNOR gate configuration within this extensive logic portfolio, maintaining pinout compatibility with industry-standard equivalents.
Replacement Considerations
Equivalent parts include the SN74AC11810D from Texas Instruments or compatible quad XNOR gates from other manufacturers such as ON Semiconductor or NXP, provided they match the 16-pin SOIC package and electrical specifications.
