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, VDD. 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.

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: 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 VSS 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
VSS v Vin v 18 V and VSS v Vout v VDD are recommended.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either VSS or VDD). Unused outputs must be left open.
