DESCRIPTION The 74VCXH16373 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 2.3 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. Bus hold on data inputs is provided in order to eliminate the need for external pull-up or pull-down resistor. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
