SN74ALS133D

Overview

The SN74ALS133D is a 16-pin Small-Outline (SOIC) integrated circuit containing a single 13-input positive-NAND gate. 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 between 3 ns and 16 ns for low-to-high transitions, and 5 ns to 47 ns for high-to-low transitions under standard load conditions.

Feature Summary

• Performs Boolean NAND logic functions across thirteen distinct input channels
• Provides active low output states when all inputs are driven high
• Compatible with standard TTL logic families through defined voltage thresholds

Applications

• Digital logic decoding circuits requiring multi-variable input processing
• Address decoding systems in microprocessor-based architectures
• Control logic gating for complex enable/disable signal generation

Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC package variant. Confirm RoHS compliance status as the base part number may have multiple packaging options with varying environmental certifications. Ensure the supplier provides valid traceability documentation matching the manufacturer's production data standards.

Selection Notes

Select this component when a single high-fan-in NAND function is required in surface-mount designs. Consider the ALS series characteristics for moderate speed and power consumption balance. Verify that the 13-input requirement matches the application logic complexity before choosing over lower-input alternatives.

Part Context

This device belongs to the Texas Instruments SN74ALS133 family of advanced low-power Schottky logic gates. It serves as the commercial-grade counterpart to the military-rated SN54ALS133, sharing identical logical functionality but differing in temperature specifications and reliability testing requirements.

Replacement Considerations

Direct substitutes include the SN74ALS133N (PDIP package) and SN74ALS133DR (tape-and-reel SOIC). Cross-reference pinouts and electrical parameters carefully when replacing with non-TI equivalents to ensure compatibility.
