74LVC1G126GV

74LVC1G126 Bus buffer/line driver; 3-state Product datasheet, Rev1.0 Aug 08, 2024 1.General Description The 74LVC1G126 is a single buffer/line driver with 3-state output. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down. 2.Features and Benefits  Wide supply voltage range from 1.65 V to 5.5 V  Overvoltage tolerant inputs to 5.5 V  High noise immunity  CMOS low power dissipation  IOFF circuitry provides partial Power-down mode operation  ±24 mA output drive (VCC = 3.0 V)  Latch-up performance exceeds 100 mA  Direct interface with TTL levels  Complies with JEDEC standard: • JESD8-7 (1.65 V to 1.95 V) • JESD8-5 (2.3 V to 2.7 V) • JESD8C (2.7 V to 3.6 V) • JESD36 (4.5 V to 5.5 V)  ESD protection: • HBM ANSI/ESDA/JEDEC JS-001 Class 3B exceeds 8000 V • MM JESD22-A115C Class C exceeds 550 V • CDM ANSI/ESDA/JEDEC JS-002 Class C3 exceeds 2000 V  Multiple package options Rev. 1.0 – Aug 08, 2024 1 74LVC1G126 Bus buffer/line driver; 3-state Rev. 1.0 – Aug 08, 2024 2 74LVC1G126 Bus buffer/line driver; 3-state 3.Ordering Information Table 1.
