Product specification  
Octal registered transceiver, inverting (3-State)  
74ABT2953  
FEATURES  
8-bit registered transceiver  
DESCRIPTION  
The 74ABT2953 high-performance BiCMOS device combines low  
static and dynamic power dissipation with high speed and high  
output drive.  
Independent registers for A and B buses  
Output capability: +64mA/–32mA  
The 74ABT2953 device is an 8-bit registered inverting transceiver.  
Two 8-bit back-to-back registers store data flowing in both directions  
between two bidirectional buses. Data applied to the inputs is  
entered and stored on the rising edge of the Clock (CPXX) provided  
that the Clock Enable (CEXX) is Low. The data is then present at  
the 3-State output buffers, but is only accessible when the Output  
Enable (OEXX) is Low. Data flow from A inputs to B outputs is the  
same as for B inputs to A outputs.  
Latch-up protection exceeds 500mA per Jedec Std 17  
ESD protection exceeds 2000V per MIL STD 883 Method 3015  
and 200V per Machine Model  
Live insertion/extraction permitted
