74VCX162374TTR

LOW VOLTAGE CMOS 16-BIT D-TYPE FLIP-FLOP (3-STATE) WITH 3.6V TOLERANT INPUTS AND OUTPUTS

STMicroelectronics 

74VCX162374

The device circuits is including 26Ω series

resistance in the outputs. These resistors permit

to reduce line noise in high speed applications.

INPUT AND OUTPUT EQUIVALENT CIRCUIT

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
