TC4049B HEX BUFFER/CONVERTER (Inverting Type)

TC4050B HEX BUFFER/CONVERTER (Non - Inverting Type)

TC4049B, TC4050B contain six circuits of buffers. TC4049B is inverter type and TC4050B is non-inverter type.

Since one TTL or DTL can be directly driven having large output current, these are useful for interfacing from CMOS to TTL or DTL. As voltage up to VSS + 18 volts can be applied to the input regardless of VDD, these can be also used as the level converter IC’s which converts CMOS logical circuits of 15 volts or 10 volts system to CMOS/TTL logical circuits of 5 volts system.

Ideal switching characteristic has been obtained by the circuit diagram of three stage inverters for TC4049B and two stage inverters for TC4050B.
