74LCX162373: Low Voltage 16-Bit Transparent Latch with 5V Tolerant Inputs and Outputs and 26 Ohm Series Resistor

The LCX162373 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 LCX162373 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The 26ohm series resistor in the output helps reduce output overshoot and undershoot.     The LCX162373 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
