SL74HCT126

Quad 3-State Noninverting Buffers

High-Performance Silicon-Gate CMOS

The SL74HCT126 is identical in pinout to the LS/ALS126. The

SL74HCT126 may be used as a level converter for interfacing TTL or

NMOS outputs to High Speed CMOS inputs.

The SL74HCT126 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-high.

• 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
