Product Summary
The MC14049U hex inverter/buffer is constructed with MOS P–channel and N–channel enhancement mode devices in a single monolithic structure. This complementary MOS device finds primary use where low power dissipation and/or high noise immunity is desired. The MC14049U provides 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 MC14049U is used as CMOS–to–TTL/DTL converters (VDD = 5.0 V, VOL=0.4 V, IOL=3.2 mA). Note that pins 13 and 16 are not connected internally on this device; consequently connections to these terminals will not affect circuit operation.
