DESCRIPTION/ORDERING INFORMATION
This 16-bit transparent D-type latch is designed for
1.65-V to 3.6-V V
CC
operation.
The SN74ALVCH16373 is particularly suitable for
implementing buffer registers, I/O ports, bidirectional
bus drivers, and working registers. This 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.

To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

16-BIT TRANSPARENT D-TYPE LATCH
WITH 3-STATE OUTPUTS
SCES020I–JULY 1995–REVISED NOVEMBER 2005
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

nor

the
buslines
high-impedance state and the increased drive provide
the capability to drive bus lines without need for
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.
significantly.
The
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.
