74VCX16841 - Low Voltage 20-Bit Transparent Latch

Download the 74VCX16841 datasheet PDF. This datasheet also covers the 74VCX variant, as both devices belong to the same low voltage 20-bit transparent latch family and are provided as variant models within a single manufacturer datasheet.

General Description

The VCX16841 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.

74VCX16841 Low Voltage 20-Bit Transparent Latch with 3.6V Tolerant Inputs and Outputs March 1998 Revised April 1999 74VCX16841 Low Voltage 20-Bit Transparent Latch with 3.6V Tolerant Inputs and Outputs General Description The VCX16841 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 74VCX16841 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O compatibility up to 3.6V.
