Hex Buffer
The MC14049B Hex Inverter/Buffer and MC14050B Noninverting Hex
Buffer are constructed with MOS PâChannel and NâChannel 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 inputâsignal high level (VIH) can exceed the VDD supply voltage for
v logic level conversions. Two TTL/DTL loads can be driven when the devices
are used as a CMOSâtoâTTL/DTL converter (VDD = 5.0 V, VOL 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.
