Input/Output standards - Definition

This is a list of electrical input/output standards that have more or less well-defined electrical properties like operating voltage, driving current, level switching behavior, circuit implementation etc., or are (industry) standards.

Different classes: single-ended, differential, voltage-referenced.

• Bus-hold
• Center Tap Terminated (CTT)
• Complementary Metal Oxide Semiconductor (CMOS)
• Current Mode Logic (CML)
• Digital Visual Interface (DVI)
• Emitter coupled logic (ECL)
• FireWire (IEEE1394)
• Gunning Transceiver Logic Plus (GTL+)
• Gunning Transceiver Logic Terminated (GTL)
• High-Speed Transceiver Logic (HSTL)
• Low Voltage CMOS (LVCMOS)
• Low voltage differential signaling (LVDS)
• Low Voltage Positive Referenced Emitter Coupled Logic (LVPECL)
• Low Voltage Transistor-Transistor Logic (LVTTL)
• Open collector
• Open drain
• Peripheral Component Interconnect (PCI)
• Positive Referenced Emitter Coupled Logic (PECL)
• Push-pull output
• Stub Series Terminated Logic (SSTL)
• Sustained tri-state
• Transistor-transistor logic (TTL)
• Tri-state
• Universal Serial Bus (USB)
