TC74VCX74FK Datasheet Low-voltage Dual D-type Flip-flop

Manufacturer: Toshiba

Overview: TC74VCX74FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX74FT, TC74VCX74FK Low-Voltage Dual D-Type Flip-Flop with 3.6-V Tolerant Inputs and Outputs The TC74VCX74FT/FK is a high-performance CMOS D-type flip-flop which is guaranteed to operate from 1.2-V to 3.6-V. Designed for use in 1.5V, 1.8V, 2.5V or 3.3V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. It is also designed with overvoltage tolerant inputs and outputs up to 3.6 V. The signal level applied to the D INPUT is transferred to Q OUTPUT during the positive going transition of the CK pulse. CLR and PR are independent of the CK and are accomplished by setting the appropriate input low. All inputs are equipped with protection circuits against static discharge.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Key Features

  • Low-voltage operation: VCC = 1.2 to 3.6 V.
  • High-speed operation: tpd = 3.5 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.6 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 9.2 ns (max) (VCC = 1.65 to 1.95 V) : tpd = 18.4 ns (max) (VCC = 1.4 to 1.6 V) : tpd = 46.0ns (max) (VCC = 1.2 V).
  • Output current: IOH/IOL = ±24 mA (min) (VCC = 3.0 V) : IOH/IOL = ±18 mA (min) (VCC = 2.3 V) : IOH/IOL = ±6 mA (min) (VCC = 1.65 V) : IOH/IOL = ±2 mA (min) (VCC = 1.4 V).
  • Latch-up performance:.
