description  
The ’ACT16544 are 16-bit registered transceivers  
that contain two sets of D-type latches for  
temporary storage of data flowing in either  
direction. They can be used as two 8-bit  
transceivers or one 16-bit transceiver. Separate  
latch-enable (LEAB or LEBA) and output-enable  
(OEAB or OEBA) inputs are provided for each  
register to permit independent control in either  
direction of data flow.

The A-to-B enable (CEAB) input must be low to  
enter data from A or to output data to B. Having  
CEAB low and LEAB low makes the A-to-B  
latches transparent; a subsequent low-to-high  
transition at LEAB puts the A latches in the  
storage mode. Data flow from B to A is similar, but  
requires using the CEBA, LEBA, and OEBA  
inputs.  
The 74ACT16544 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 54ACT16544 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
74ACT16544 is characterized for operation from –40°C to 85°C.
