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.

Stresses exceeding those listed in the Maximum Ratings table may damage the
device. If any of these limits are exceeded, device functionality should not be
assumed, damage may occur and reliability may be affected.
1. Maximum Ratings are those values beyond which damage to the device may
occur.
2. Temperature Derating:
“D/DW” Package: –7.0 mW/_C From 65_C To 125_C
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.
