74LCX374 Low Voltage Octal D-Type Flip-Flop with 5V Tolerant Inputs and Outputs February 1994 Revised April 1999 74LCX374 Low Voltage Octal D-Type Flip-Flop with 5V Tolerant Inputs and Outputs General Description The LCX374 consists of eight D-type flip-flops featuring separate D-type inputs for each flip-flop and 3-STATE outputs for bus-oriented applications. A buffered clock (CP) and Output Enable (OE) are common to all flip-flops. The LCX374 is designed for low-voltage (3.3V or 2.5V) VCC applications with capability of interfacing to a 5V signal environment. The LCX374 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. Features s 5V tolerant inputs and outputs s 2.3V–3.6V VCC specifications provided s 8.5 ns [ ... ]
