Product Overview
The Signetics LU356A is a dual 4-input expandable line driver and NAND buffer integrated circuit from the vintage Utilogic II logic family. Housed in a standard 14-pin dual in-line plastic package (DIP-14), it provides high capacitive drive capability and high noise margins for legacy computing architectures, digital instrumentation, and vintage logic restoration.
Key Features
- Dual 4-input expandable NAND line driver and buffer configuration
- Utilogic II bipolar logic architecture
- High capacitive drive capability for signal lines and bus interfaces
- High noise margin logic levels
- Standard DIP-14 through-hole package footprint
- Top face markings: Signetics logo, date code 846, LU356A
Applications
- Restoring legacy mainframe, minicomputer, or peripheral logic boards using Signetics Utilogic II silicon
- Maintaining vintage industrial automated test benches and instrumentation reliant on original DTL and Utilogic ICs
- Bench breadboarding for vintage computing enthusiasts and electronic hardware preservation projects
Frequently Asked Questions
What logic family does the LU356A belong to?
The LU356A belongs to the Signetics Utilogic II family, engineered with high capacitive drive capabilities and robust noise immunity for industrial digital systems.
What package type is this integrated circuit?
It is housed in a standard 14-pin dual in-line plastic through-hole package (DIP-14).
Why buy individual Signetics LU356A ICs instead of bulk surplus lots?
Vintage logic ICs from obsolete families like Utilogic II often require buying large mystery assortments just to find a single working line driver. Ordering here provides the exact photographed part number needed for repair work without surplus bulk. More pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, ship free once the total reaches $28, and leave our Idaho warehouse the same or next business day.
Solid vintage bipolar silicon from the golden era of discrete logic, ready to put a quiet legacy system right back on the bus.
