The SN74AUCH16374 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus
drivers, and working registers. It can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positive
transition of the clock (CLK) input, the Q outputs of the flip-flop take on the logic levels set up at the data (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.

DESCRIPTION/ORDERING INFORMATION(CONTINUED)
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors
with the bus-hold circuitry is not recommended.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
