TEXAS INSTRUMENTS SN74LVCH16373ADGGR

The SN74LVCH16373ADGGR is a 16-bit transparent D-Type Latch with 3-state outputs. It is designed for 1.65 to 3.6V VCC operation. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers and working registers. It can be used as two 8-bit latches or one 16-bit latch. When the LE input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs. A buffered OE\ input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without interface or pull-up components. OE\ does not affect internal operations of the latch. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.
