PIN CONNECTION
DESCRIPTION The 74VCX162373 is a low voltage CMOS 16 BIT D-TYPE LATCH with 3 STATE OU TPUTS NON INVERTING fabricated with sub-micron silicon gate and five-layer metal wiring C2MOS technology. It is ideal for low power and very high speed 1.8 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs. These 16 bit D-TYPE latches are bite controlled by two latch enable inputs (nLE) and tw o output enable inputs (OE). W hile the nLE input is held at a high level, the nQ outputs will follow the data input precisely. W hen the nLE is taken low, the nQ outputs will be in a normal logic state (high or low logic level) and while high level the outputs will be in a high impedance state. The device circuits is including 26 series resistance in the outputs. These resistors permit to reduce line noise in high speed applications. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
