DESCRIPTION/ORDERING INFORMATION
This 16-bit transparent D-type latch is designed for
1.65-V to 3.6-V VCC operation.
The SN74LVC16373A 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.
