Overview
The SN74AS11DR is a triple 3-input AND gate from the Texas Instruments AS logic series, housed in a surface-mount SOIC-14 package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports propagation delays as low as 6 ns. The device provides a low-level output current of 20 mA and a high-level output current of -2 mA. It functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Features three independent 3-input AND gates for complex logic implementation
- Utilizes Schottky transistor technology for high-speed switching performance
- Designed for surface-mount assembly with standard SOIC-14 footprint compatibility
Applications
- High-speed digital signal processing circuits
- Memory address decoding systems
- Control logic in industrial automation equipment
Procurement Notes
Verify the specific suffix DR indicates the SOIC-14 surface mount package variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required pin configuration and thermal specifications for the target application environment.
Selection Notes
Select this component when high-speed AND logic is required in a compact surface-mount design. Compare against the SN74LS11 for lower speed needs or SN74ACT11 for CMOS compatibility. Verify that the 20 mA output drive capability meets the load requirements of the connected circuitry.
Part Context
This device belongs to the Texas Instruments 74AS (Advanced Schottky) family, known for superior speed-power product compared to standard TTL. The SN74AS11 series provides triple 3-input AND functionality. The 'DR' suffix specifically denotes the tape-and-reel surface mount packaging format suitable for automated assembly processes.
Replacement Considerations
The SN74AS11N is the equivalent through-hole PDIP-14 version. For surface-mount alternatives, consider the SN74ACT11DR for CMOS compatibility or the SN74ALS11DR for lower power consumption while maintaining similar performance characteristics.
