Overview
The SN74AS08DBR is a quadruple 2-input positive-AND gate manufactured by Texas Instruments. It belongs to the AS logic series, utilizing bipolar technology for high-speed performance. The device operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 5.5 ns. It provides low-level output current of 8 mA and high-level output current of -8 mA. Packaged in a 14-pin SSOP format, it supports surface-mount installation and functions reliably across an operating temperature range from -40°C to +125°C.
Feature Summary
- High-speed bipolar AND gate implementation
- Wide industrial operating temperature range
- Standard TTL-compatible input levels
Applications
- Arithmetic circuits
- Memory address decoding
- Code converters
Procurement Notes
Verify the specific suffix 'DBR' corresponds to the 14-SSOP package with reel or cut-tape packaging options as documented. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the Texas Instruments component.
Selection Notes
Select this component when bipolar speed advantages are required over standard CMOS alternatives in 5V systems. The AS series offers faster switching characteristics suitable for demanding digital logic applications. Consider the SSOP package constraints for PCB layout and thermal management requirements during the design phase.
Part Context
This part is part of the SN74AS08 family of quadruple 2-input AND gates. It shares functional compatibility with other devices in the 74AS series but utilizes bipolar technology for enhanced speed. The DBR suffix specifically denotes the surface-mount SSOP package configuration offered by Texas Instruments.
Replacement Considerations
Direct substitutes include SN74AS08N (PDIP) or SN74AS08D (SOIC) for different package requirements. Cross-series replacements like SN74LS08 offer slower speeds but similar functionality.
