74LVC125A D

74LVC125A
Low-Voltage CMOS
Quad Buffer
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
www.onsemi.com
The 74LVC125A is a high performance, non−inverting quad buffer
operating from a 1.2 to 3.6 V supply. High impedance TTL compatible
inputs significantly reduce current loading to input drivers while TTL
compatible outputs offer improved switching noise performance. A VI
specification of 5.5 V allows 74LVC125A inputs to be safely driven
from 5.0 V devices. The 74LVC125A is suitable for memory address
driving and all TTL level bus oriented transceiver applications.
Current drive capability is 24 mA at the outputs. The Output Enable
(OEn) inputs, when HIGH, disable the outputs by placing them in a
HIGH Z condition.
