The device is byte controlled. A buffered clock (CP) and output enable (OE) are common to each byte and can be shorted together for full 16-bit operation. The VCX162374 is also designed with 26: series resistors in the outputs. This design reduces line noise in applications such as memory address drivers, clock drivers and bus transceivers/transmitters. The 74VCX162374 is designed for low voltage (1.4V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74VCX162374 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. Features s 1.4V-3.6V VCC supply operation s 3.6V tolerant inputs and outputs s 26: series resistors in outputs s tPD (CLK to O n) 3.4 ns max for 3.0V to 3.6V VCC s Power-off high impedance inputs and outputs s Supports live insertion and withdrawal (Note 1) s Static Drive (IOH/IOL) r12 mA @ 3.0V VCC s Uses patented noise/EMI reduction circuitry s Latch-up performance exceeds 300 mA s ESD performance: Human body model ! 2000V Machine model ! 200V Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

The device is byte controlled with each byte functioning identically, but independent of the other. The control pins can be shorted together to obtain full 16-bit operation. Each clock has a buffered clock and buffered Output Enable common to all flip-flops within that byte. The description which follows applies to each byte. Each flipflop will store the state of their individual I inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CPn) transition. With the Output Enable (OEn) LOW, the contents of the flip-flops are available at the outputs. When OEn is HIGH, the outputs go to the high impedance state. Operations of the OEn input does not affect the state of the flip-flops.
