74LCX16841
Low Voltage 20-Bit Transparent Latch with 5V Tolerant Inputs and Outputs

General Description

The LCX16841 contains twenty 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 LCX16841 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment.

The LCX16841 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
