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 ≤ 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.
