74ALVC125D
Quad buffer/line driver; 3-state
General descriptionThe 74ALVC125isa quad non-inverting buffer/line driver with 3-state outputs. The 3-state
outputs (nY) are controlled by the output enable input (nOE). A HIGH on the nOE pin
causes the outputs to assume a high-impedance OFF-state. Features Wide supply voltage range from 1.65 V to 3.6V 3.6 V tolerant inputs/outputs CMOS low power consumption Direct interface with TTL levels (2.7 V to 3.6V) Power-down mode Latch-up performance exceeds 250 mA Complies with JEDEC standards: JESD8-7 (1.65 V to 1.95V) JESD8-5 (2.3 V to 2.7V) JESD8B/JESD36 (2.7 V to 3.6V) ESD protection: HBM JESD22-A114E exceeds 2000V MM JESD22-A 115-A exceeds 200V Ordering information
