                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, 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 devices
                are used as a CMOS–to–TTL/DTL converter (VDD = 5.0 V, VOL
                v
                0.4 V,
                IOL
                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.
