74HC125; 74HCT125 Quad buffer/line driver; 3-state Rev. 6 1 December 2015 Product data sheet 1. General description The 74HC125; 74HCT125 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. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2. Features and benefits  Complies with JEDEC standard no. 7A  Input levels:  The 74HC125: CMOS levels  The 74HCT125: TTL levels  ESD protection:  HBM JESD22-A114F exceeds 2000 V  MM JESD22-A115-A exceeds 200 V  Multiple package options  Specified from 40 C to +85 C and from 40 C to +125 C 3.
