SL74HCT125
Quad 3-State Noninverting Buffers
High-Performance Silicon-Gate CMOS
The SL74HCT125 is identical in pinout to the LS/ALS125. The
SL74HCT125 may be used as a level converter for interfacing TTL or
NMOS outputs to High Speed CMOS inputs.
The SL74HCT125 noninverting buffers are designed to be used with
3-state memory address drivers, clock drivers, and other bus-oriented
systems. The devices have four separate output enables that are active-
low.
• TTL/NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA
