AN10161: PicoGate Logic Footprints
Comparison of 5-pin, 6-pin, and 8-pin small-outline logic packages across multiple vendors to ensure footprint compatibility for single, dual, and triple-gate devices.
Overview
This application note provides a detailed comparison of small-outline logic packages used for single-, dual-, and triple-gate devices. It reconciles different naming conventions used by major suppliers including NXP (PicoGate), Texas Instruments (TinyLogic), Fairchild (Little Logic), ON Semiconductor (MiniGate), and Toshiba (LMOS). The document outlines dimensions for 5-pin, 6-pin, and 8-pin packages across 0.95 mm, 0.65 mm, and 0.5 mm lead pitches. Technical tables compare package outlines such as SOT353, SC70, SC88A, SOT323, USV, SOT753, SOT23, SM8, SSOP8, and VSSOP8, confirming that these parts are footprint compatible despite varying industry designations.
Use Cases
- Cross-referencing logic components from multiple semiconductor vendors
- PCB footprint design and verification for small-scale logic gates
- Identifying second-source alternatives for SOT and SC series packages
- Standardizing layout footprints for 5, 6, and 8-pin logic devices
