MC14049B, MC14050B
Hex Buffer
The MC14049B Hex Inverter/Buffer and MC14050B Noninverting
Hex Buffer are constructed with MOS P−Channel and N−Channel
enhancement mode devices in a single monolithic structure. These
complementary MOS devices find primary use where low power
dissipation and/or high noise immunity is desired. These devices
provide logic level conversion using only one supply voltage, V
DD
.
The input−signal high level (V
IH
) can exceed the V
DD
supply
voltage for logic level conversions. Two TTL/DTL loads can be driven
when the devices are used as a CMOS−to−TTL/DTL converter
(V
DD
= 5.0 V, V
OL
≤
0.4 V, I
OL
≥
3.2 mA).
Note that pins 13 and 16 are not connected internally on these
devices; consequently connections to these terminals will not affect
circuit operation.

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. Temperature Derating: See Figure 3.
This device contains protection circuitry to protect the inputs against damage
due to high static voltages or electric fields referenced to the V
SS
pin only. Extra
precautions must be taken to avoid applications of any voltage higher than the
maximum rated voltages to this high−impedance circuit. For proper operation, the
ranges V
SS
≤
V
in
≤
18 V and V
SS
≤

≤

are recommended.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V
SS
or V
DD
). Unused outputs must be left open.
