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:

_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

Unused inputs must always be tied to an appropriate logic voltage level
