Product Overview
Motorola SN74LS05N is a low-power Schottky TTL integrated circuit containing six independent inverters with open-collector outputs. Built in a standard 14-pin dual in-line package (DIP-14), this device requires external pull-up resistors to perform standard logic inversions, drive indicator loads, or interface between differing logic voltage domains.
Key Features
- Six independent logic inverter channels
- Open-collector output configuration for wire-AND logic and level shifting
- Standard Low-Power Schottky TTL (74LS) technology
- Through-hole 14-pin dual inline package (DIP-14)
- 5.0V nominal logic supply voltage
Applications
- Bench restoration and repair of vintage arcade boards, computing equipment, and classic digital synthesizers
- Interfacing 5V TTL systems with higher-voltage digital circuits or indicator lamps via external pull-up resistors
- Breadboard prototyping for electronics hobbyists constructing discrete logic gates and clock generators
Frequently Asked Questions
What output configuration does the SN74LS05N feature?
This chip features open-collector outputs rather than standard totem-pole stages. An external pull-up resistor is required on each output line to produce a high logic state or establish a connection to a specific pull-up voltage.
Can this IC directly replace a standard 74LS04?
No. While pin-compatible, the 74LS04 uses standard totem-pole active outputs, whereas the 74LS05 uses open-collector outputs that require external pull-up resistors to generate a high logic level.
Why buy a single pull rather than a bulk surplus lot?
When repairing legacy hardware or testing a prototype, you often just need one specific chip without buying an unsorted bulk pack. Flat-rate shipping is $8, orders over $28 ship free, and orders leave our Idaho warehouse the same or next business day.
Classic TTL logic that helped power an entire generation of digital design. Straightforward, dependable silicon ready to restore your next vintage project.
Shipping? $8 flat rate, free once your order passes $28 - and it leaves the Idaho warehouse the same or next business day.
