SEMICONDUCTOR TECHNICAL DATA
Hex Buffer
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
v 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.
• High Source and Sink Currents
• High–to–Low Level Converter
• Supply Voltage Range = 3.0 V to 18 V
• VIN can exceed VDD
