74VHC125; 74VHCT125 Quad buffer/line driver; 3-state Rev. 02 — 13 October 2009 Product data sheet 1. General description The 74VHC125; 74VHCT125 are high-speed Si-gate CMOS devices and are pin compatiblewithLow-powerSchottkyTTL(LSTTL).Theyarespecifiedincompliancewith JEDEC standard JESD7-A. The 74VHC125; 74VHCT125 provides four non-inverting buffer/line drivers with 3-state outputs.The3-stateoutputs(nY)arecontrolledbytheoutputenableinput(nOE).AHIGH at nOE causes the outputs to assume a high-impedance OFF-state. The74VHC125;74VHCT125areidenticaltothe74VHC126;74VHCT126buthaveactive LOW enable inputs. 2. Features n Balanced propagation delays n All inputs have a Schmitt-trigger action n Inputs accepts voltages higher thanV CC n Input levels: u The 74VHC125 operates with CMOS logic levels u The 74VHCT125 operates with TTL logic levels n ESD protection: u HBM JESD22-A114E exceeds 2000V u MM JESD22-A115-A exceeds 200V u CDM JESD22-C101C exceeds 1000V n Multiple package options n Specified from-40 (cid:176)C to +85 (cid:176)C and from -40 (cid:176)C to +125 (cid:176)C 3.
