This 16-bit transparent D-type latch is operational at
0.8-V to 2.7-V VCC, but is designed specifically for
1.65-V to 1.95-V VCC operation.
The SN74AUC16373 is particularly suitable for
implementing buffer registers, I/O ports, bidirectional
bus drivers, and working registers. The device can be
used as two 8-bit latches or one 16-bit latch. When
the latch-enable (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 output-enable (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 pullup 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.
