SN74ALS133NSR

Overview

The SN74ALS133NSR is a single 13-input positive-NAND gate from the Texas Instruments ALS logic family, housed in a 16-pin Small Outline Package (SOP). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features a low-level output current capability of up to 8 mA and a high-level output current of -0.4 mA. Propagation delays are specified with maximum values of 11 ns for low-to-high transitions and 25 ns for high-to-low transitions under standard load conditions.

Feature Summary

• Implements Boolean NAND logic functions using thirteen distinct input terminals.
• Provides active low output states when all inputs are driven high.
• Utilizes Advanced Low-Power Schottky technology for optimized power-speed performance.

Applications

• Digital logic circuit design requiring multi-variable decision making
• Address decoding systems utilizing multiple address lines
• Control logic implementation in industrial automation equipment

Procurement Notes

Verify that the ordering suffix NSR corresponds specifically to the SOP package variant. Confirm RoHS compliance status and lead finish specifications against the latest manufacturer documentation. Ensure the procurement channel provides valid traceability records for production-grade components.

Selection Notes

Select this component when a single gate with extensive input capacity is required. Compare propagation delay specifications against system timing requirements. Evaluate power consumption characteristics relative to other logic families. Verify physical footprint compatibility during PCB layout planning.

Part Context

This part belongs to the SN74ALS series, representing advanced low-power Schottky logic devices manufactured by Texas Instruments. The series offers improved switching speeds compared to standard LS logic while maintaining lower power dissipation than original ALS variants. The specific model integrates a single complex gate function into a compact surface-mount form factor.

Replacement Considerations

SN74ALS133N serves as a through-hole equivalent. SN74ALS133DR is available in SOIC packaging. SN54ALS133 provides military-grade temperature range options. Verify pinout compatibility before substituting across different package types or temperature grades.
