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
v 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.

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

V

18 V and V

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.
