{"product_id":"sn74ls125adr2","title":"SN74LS125ADR2","description":"\u003cp\u003eThe SN74LS125ADR2 from Motorola is a quad non-inverting buffer with 3-state outputs, part of the classic 74LS Low-power Schottky logic family. It operates at a standard 5V supply (4.75V to 5.25V), making it compatible with TTL logic systems. Each channel can source 2.6mA and sink 24mA, providing robust drive for bus lines and TTL loads. The 3-state outputs allow for bus multiplexing and isolation. Housed in a 14-pin SOIC package, it is designed for commercial applications with an operating temperature range of 0°C to 70°C.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e3-State Outputs: Enables bus sharing and isolation in multi-device 5V systems.\u003c\/li\u003e\n\u003cli\u003eHigh 24mA Sink Current: Drives TTL loads and long bus lines effectively.\u003c\/li\u003e\n\u003cli\u003eStandard 5V Operation: Directly compatible with legacy TTL logic and 5V microcontrollers.\u003c\/li\u003e\n\u003cli\u003eLow-Power Schottky Technology: Provides a good balance of speed and power consumption for 5V designs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eLegacy 5V Bus Systems\u003c\/h3\u003e\u003cp\u003eIdeal for buffering data and address buses in legacy 5V microprocessor systems, ensuring signal integrity and providing the necessary drive current for multiple loads.\u003c\/p\u003e\u003ch3\u003eTTL-to-CMOS Interfacing\u003c\/h3\u003e\u003cp\u003eWith its 5V operation and 3-state outputs, it can interface between TTL logic and CMOS logic, ensuring proper voltage levels and preventing damage to sensitive inputs.\u003c\/p\u003e\u003ch3\u003eMemory Expansion in Retro Computing\u003c\/h3\u003e\u003cp\u003eUse it to buffer address lines when expanding memory in vintage computers or hobbyist projects.
