description
The ’AHC16373 devices are 16-bit transparent
D-type latches with 3-state outputs designed
specifically for driving highly capacitive or
relatively
low-impedance
loads.
They
are
particularly suitable for implementing buffer
registers, I/O ports, bidirectional bus drivers, and
working registers.
These devices 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 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 the increased drive provide the capability to drive bus
lines without need for interface or pullup components.
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.
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.
The SN54AHC16373 is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74AHC16373 is characterized for operation from –40
°C to 85°C.
