Overview
The SN74AS00DR is a quadruple 2-input positive-NAND gate from the Texas Instruments SN74AS series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 4.5 ns at 5 V with 50 pF load capacitance. The device provides a low-level output current of 20 mA and a high-level output current of -2 mA. It is housed in a 14-SOIC package and supports surface-mount installation. The component functions reliably across an operating temperature range of 0°C to +70°C.
Feature Summary
- Ultra-high-speed logic performance with propagation delays under 5 ns
- Bipolar input technology for robust signal handling
- Push-pull output configuration for strong drive capability
Applications
- High-speed digital logic circuits requiring fast switching times
- Data acquisition systems utilizing NAND gate functionality
- Industrial control applications operating within standard TTL voltage levels
Procurement Notes
Verify the specific suffix DR indicates the SOIC-14 tape-and-reel packaging format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design accommodates the bipolar input characteristics and specified current limits for reliable operation within the defined temperature range.
Selection Notes
Select this component when ultra-high speed is required compared to standard or ALS variants. The AS series offers faster propagation delays but consumes more power than CMOS alternatives. Verify that the system power supply remains strictly within the 4.5 V to 5.5 V range to maintain timing specifications and prevent damage.
Part Context
This part belongs to the SN74AS family, known for advanced Schottky technology providing high speed. It serves as a surface-mount alternative to the through-hole SN74AS00N. The DR suffix specifically denotes the reel-packaged version of the standard SN74AS00D device, facilitating automated assembly processes.
Replacement Considerations
SN74AS00NSR is a compatible reel-packaged variant from the same manufacturer.
