Low-Voltage Octal D-Type Flip-Flop with 5-V Tolerant Inputs and Outputs
   
The TC74LCX374 is a high-performance CMOS octal D-type flip-flop. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation.
The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5-V supply environment for both inputs and outputs.
   
Features
• Low-voltage operation: VCC = 2.0 to 3.6 V
• High-speed operation: tpd = 8.5 ns (max) (VCC = 3.0 to 3.6 V)
• Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V)
• Latch-up performance: −500 mA
• Available in JEITA SOP, TSSOP and VSSOP (US)
• Power-down protection provided on all inputs and outputs
• Pin and function compatible with the 74 series
