Product specification  
Octal latched transceiver with dual enable,  
inverting (3-State)  
74ABT544  
FEATURES  
FUNCTIONAL DESCRIPTION  
ESD protection exceeds 2000 V per MIL  
The ’ABT544 contains two sets of eight  
D–type latches, with separate control pins for  
each set. Using data flow from A to B as an  
example, when the A-to-B Enable (EAB)  
input and the A-to-B Latch Enable (LEAB)  
input are Low the A-to-B path is transparent.  
A subsequent Low-to-High transition of the  
LEAB signal puts the A data into the latches  
where it is stored and the B outputs no longer  
change with the A inputs. With EAB and  
OEAB both Low, the 3-State B output buffers  
are active and invert the data present at the  
outputs of the A latches.  
STD 883 Method 3015 and 200 V per  
Combines 74ABT245 and 74ABT373 type  
Machine Model  
functions in one device  
8-bit octal transceiver with D-type latch  
Back-to-back registers for storage  
DESCRIPTION  
The 74ABT544 high-performance BiCMOS  
device combines low static and dynamic  
power dissipation with high speed and high  
output drive.  
Separate controls for data flow in each  
direction  
Output capability: +64mA/–32mA  
Live insertion/extraction permitted  
Power-up 3-State  
The 74ABT544 Octal Registered Transceiver  
contains two sets of D-type latches for  
temporary storage of data flowing in either  
direction. Separate Latch Enable (LEAB,  
LEBA) and Output Enable (OEAB, OEBA)  
inputs are provided for each register to  
permit independent control of data transfer in  
either direction. The outputs are guaranteed  
to sink 64mA.  
Power-up reset  
Control of data flow from B to A is similar, but  
using the EBA, LEBA, and OEBA inputs.  
Latch-up protection exceeds 500mA per  
Jedec JC40.2 Std 17
