MC74HCT125A
Quad 3-State Noninverting
Buffer with LSTTL
Compatible Inputs
High−Performance Silicon−Gate CMOS
http://onsemi.com
The MC74HCT125A is identical in pinout to the LS125. The device
inputs are compatible with standard CMOS and LSTTL outputs.
The MC74HCT125A noninverting buffer is 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.

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance circuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
