Overview
The SN74AHC08RGYR is a quad 2-input AND gate manufactured by Texas Instruments, belonging to the AHC logic series. It operates within a supply voltage range of 2 V to 5.5 V and features low dynamic power consumption. The device provides high noise immunity and is housed in a 14-VQFN package with a 3.5x3.5 mm footprint. Key electrical parameters include a propagation delay of 6 ns at 5 V and output drive currents of ±8 mA. It supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides four independent 2-input AND logic functions for signal processing
- Operates across a wide supply voltage range from 2 V to 5.5 V
- Features low static power consumption and high noise immunity
- Compatible with standard CMOS logic families
Applications
- Digital signal gating and control logic circuits
- Memory address decoding systems
- General-purpose logic applications in consumer electronics
- Industrial control system interfaces
Procurement Notes
Verify the specific suffix RGYR corresponds to the 14-VQFN package variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure moisture sensitivity level (MSL) requirements are met for surface-mount assembly processes. Cross-reference the datasheet revision date to ensure current specifications.
Selection Notes
Select this component when a quad 2-input AND function is required in a compact surface-mount package. The AHC series offers faster switching speeds compared to standard HC devices while maintaining compatibility. Consider the 2 V to 5.5 V operating range for versatile power supply integration. Evaluate the 14-VQFN form factor for space-constrained PCB layouts.
Part Context
This part belongs to the Texas Instruments SN74AHC family of advanced high-speed CMOS logic devices. The AHC series is designed to replace older HC/HCT technologies with improved performance characteristics. The SN74AHC08 specifically implements the standard AND gate truth table across four independent channels within a single integrated circuit package.
Replacement Considerations
Direct pin-compatible alternatives may include other quad 2-input AND gates from the same or similar logic families, provided voltage levels and package dimensions match. Verify functional equivalence before substitution.
