ON MC74HC125A Quad 3-state noninverting buffer Datasheet

MC74HC125A,
MC74HC126A
Quad 3-State Noninverting
Buffers
High−Performance Silicon−Gate CMOS
The MC74HC125A and MC74HC126A are identical in pinout to
the LS125 and LS126. The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with
LSTTL outputs.
The HC125A and HC126A 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 (HC125A) or active−high (HC126A).

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.
