Overview
The MC74HCT125ADR2G is a quad 3-state noninverting buffer produced by onsemi. This device is part of the MC74HCT series, which is designed to be compatible with standard CMOS and TTL outputs. It is particularly useful in bus-oriented systems, such as memory address drivers and clock drivers. The MC74HCT125A, which this package variant is based on, features four separate output enables that are active-low, allowing for flexible control over the output states.
