74HC133D-G

Overview

The Rochester Electronics 74HC133D-G is a high-speed silicon-gate CMOS logic device providing a 13-input NAND function. It is pin-compatible with low-power Schottky TTL (LSTTL) and complies with JEDEC standard no. 7A. The component features standard output capability and belongs to the SSI ICC category, designed for robust digital logic applications requiring multiple input processing within a compact integrated circuit form factor.

Feature Summary

• Provides a dedicated 13-input NAND logic function
• High-speed silicon-gate CMOS technology
• Pin-compatible with LSTTL standards

Applications

• Digital logic circuits requiring multi-input NAND operations
• System designs needing LSTTL pin compatibility
• SSI category signal processing

Procurement Notes

Verify the specific manufacturer date code and lot traceability upon receipt, as Rochester Electronics sources components from various original manufacturers. Confirm that the package marking matches the 74HC133D-G designation to ensure authenticity. Request the official datasheet or test data sheet associated with the specific production batch to validate electrical parameters against current application requirements before final integration.

Selection Notes

Select this component when a single gate must handle thirteen inputs in a CMOS environment while maintaining physical interchangeability with legacy LSTTL footprints. Ensure the design accommodates the specific voltage levels and switching speeds inherent to HC series devices rather than older bipolar technologies.

Part Context

This part belongs to the 74HC family of high-speed CMOS logic gates. The 74HC133 variant specifically addresses complex gating needs by consolidating thirteen inputs into one output, reducing board space compared to cascading multiple standard two-input NAND gates.

Replacement Considerations

Compatible substitutes include MM74HC133, DM74ALS133, and M54HC133, provided they meet the same 13-input NAND specification and package constraints.
