74LVT125 74LVTH125 3.3 V quad buffer 3-state Rev. 8 18 August 2021 Product data sheet 1. General description The 74LVT125 74LVTH125 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). A HIGH on nOE causes the outputs to assume a high impedance OFF-state. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs. This device is fully specified for partial power down applications using I . The I circuitry disables OFF OFF the output, preventing the potentially damaging backflow current through the device when it is powered down. 2. Features and benefits Quad bus interface 3-state buffers Wide supply voltage range from 2.7 to 3.6 V BiCMOS high speed and output drive Output capability: +64 mA and -32 mA Direct interface with TTL levels Overvoltage tolerant inputs to 5.5 V Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs Live insertion and extraction permitted No bus current loading when output is tied to 5 V bus Power-up 3-state I circuitry provides partial Power-down mode operation OFF Latch-up performance exceeds 500 mA per JESD 78 Class II Level B Complies with JEDEC standard JESD8C (2.7 V to 3.6 V) ESD protection: HBM EIA/JESD22-A114-A exceeds 2000V MM EIA/JESD22-A115-A exceeds 200V Specified from -40 C to 85 C 3.
