SN54ACT16373 に関する概要
The SN54ACT16373 and 74ACT16373 are 16-bit D-type transparent 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. The Q outputs of the latches follow the data (D) inputs if enable C is taken high. When C is taken low, the Q outputs are latched at the levels set up at the D inputs.
A buffered output-enable 
input can be used to place the 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 in a bus-organized system
without need for interface or pullup components.
does not
affect the internal operations of the latches. Old data can be
retained or new data can be entered while the outputs are in the
high-impedance state.
The 74ACT16373 is packaged in TI's shrink small-outline package, which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area.
The SN54ACT16373 is characterized for operation over the full military temperature range of -55°C to 125°C. The 74ACT16373 is characterized for operation from -40°C to 85°C.
