MC14503B
Hex Non-Inverting 3-State
Buffer
The MC14503B is a hex non–inverting buffer with 3–state outputs, and a
high current source and sink capability. The 3–state outputs make it useful in
common bussing applications. Two disable controls are provided. A high
level on the Disable A input causes the outputs of buffers 1 through 4 to go
into a high impedance state and a high level on the Disable B input causes
the outputs of buffers 5 and 6 to go into a high impedance state.

ONE OF TWO/FOUR BUFFERS
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 VSS
≤
(Vin or Vout)
≤
VDD.
Unused inputs must always be tied to an appropriate logic voltage
level (e.g., either VSS or VDD). Unused outputs must be left open.
