74LCXH162373 Low Voltage 16-Bit Transparent Latch with Bushold and 26 Series Resistor Outputs
General Description
The LCXH162373 contains sixteen non-inverting latches with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. The flip-flops appear transparent to the data when the Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the outputs are in a high impedance state. The LCXH162373 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The 26 series resistor helps reduce output overshoot and undershoot. The LCXH162373 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. The LCXH162373 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.
