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 ≤ 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.
