description
The ’AHC16373 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 a 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.
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.
