Hex Buffers
The MC14049UB hex inverter/buffer is constructed with MOS
P–channel and N–channel enhancement mode devices in a single
monolithic structure. This complementary MOS device finds primary
use where low power dissipation and/or high noise immunity is
desired. This device provides logic–level conversion using only one
supply voltage, V
DD
. The input–signal high level (VIH) can exceed the
VDD supply voltage for logic–level conversions. Two TTL/DTL
Loads can be driven when the device is used as CMOS–to–TTL/DTL
converters (VDD = 5.0 V, VOL v 0.4 V, IOL ≥ 3.2 mA). Note that pins
13 and 16 are not connected internally on this device; consequently
connections to these terminals will not affect circuit operation.

2. Maximum Ratings are those values beyond which damage to the device
may occur.

All Packages: See Figure 4.
This device contains 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

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