Since the launch of the first Standard CMOS series (4000 series),
Toshiba has released successive generations of high-speed and low-voltage CMOS logic ICs.
Toshiba continues to supply CMOS logic ICs with a wide operating range (1.2 V to 18 V) suitable for various applications.
FAQ : What are the differences among the general-purpose logic IC series?

*1: Maximum propagation delay time of typical ICs (TC4001, 74HC244, TC74AC244, 74VHC244, 74LCX244, and TC74VCX244) at 85°C, except for the TC4001 for which the maximum propagation delay time at 25°C is shown
*2: Those output current values are from DC characteristics table of the datasheet. Absolute maximum rated output current is specified separately.
*3: The terms “tolerant function” and “power-down protection” are sometimes used interchangeably. The input- and output-tolerant functions may be referred to as input and output power-down protection, respectively.
*4: TC4049BF/BP, TC4050BF/BP, TC74HC4049BP/BF/BFT, 74HC4049D, TC74HC4050BP/BF/BFT and 74HC4050D have the input-tolerant function that allows level shifting from a higher voltage to a lower voltage.
