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, V
.
The input-signal high level (V
) can exceed the V
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 (V
= 5.0 V, V
OL >=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.
