3.3V, 16-Bit D-Type Transparent Latch with 3-State Outputs
GENERAL DESCRIPTION

The 74LVTH16373 is a 16-bit high-performance D-type transparent latch with non-inverting 3-state outputs designed for 3.3V VCC operation. The device can be used for driving loads with high capacitance or relatively low-impedance, making it suitable for applications in buffer registers, I/O ports, bidirectional bus drivers and working registers.

The device can be operated as two 8-bit latches or one 16-bit latch. When latch enable input nLE is set high, the outputs nQn will indicate the data of inputs nDn. When nLE is set low, the nQn outputs will be latched at the levels of the inputs nDn one setup time before the High-to-Low transition.

The output enable nOE input can make all outputs in high/low logic levels or high-impedance state. The bus hold on data inputs eliminates the need for external pull-up/pull-down resistors to hold unused inputs.
