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.
