Quad buffer/line driver; 3-state
1. General descriptionThe 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 2000V MM JESD22-A115-A exceeds 200V Multiple package options Specified from 40 C to +85 C and from 40 C to +125C
