74LVC126A Quad buffer/line driver with 5 V tolerant input/outputs; 3-state Rev. 8 -- 8 April 2014 Product data sheet 1. General description The 74LVC126A consists of four non-inverting buffers/line drivers with 3-state outputs, which are controlled by the output enable input (nOE). A LOW at nOE causes the outputs to assume a high-impedance OFF-state. Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. 2. Features and benefits 5 V tolerant inputs/outputs for interfacing with 5 V logic Wide supply voltage range from 1.2 V to 3.6 V CMOS low power consumption Direct interface with TTL levels Complies with JEDEC standard: JESD8-7A (1.65 V to 1.95 V) JESD8-5A (2.3 V to 2.7 V) JESD8-C/JESD36 (2.7 V to 3.6 V) ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115B exceeds 200 V CDM JESD22-C101E exceeds 1000 V Specified from 40 C to +85 C and 40 C to +125 C 3.
