74LCXH162374 Low Voltage 16-Bit D-Type Flip-Flop with Bushold and 26 Series Resistors in Outputs
February 2001 Revised October 2001
74LCXH162374 Low Voltage 16-Bit D-Type Flip-Flop with Bushold and 26 Series Resistors in Outputs
General Description
The LCXH162374 contains sixteen non-inverting D-type flip-flops with 3-STATE outputs and is intended for bus oriented applications. 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 LCXH162374 is designed for low voltage (2.5V or 3.3V) VCC applications. The LCXH162374 data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. The 26 series resistor in the output helps reduce output overshoot and undershoot. The LCXH162374 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.

Functional Description
The LCXH162374 consists of sixteen edge-triggered flip-flops with individual D-type inputs and 3-STATE true outputs. 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 byte 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 flip-flop will store the state of their individual D 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. Operation of the OEn input does not affect the state of the flip-flops.
