FEATURES  
• 8-bit registered transceivers  
DESCRIPTION  
The 74F2952 and 74F2953 are 8-bit registered transceivers. Two  
8-bit back-to-back registers store data flowing in both directions  
between two bi-directional 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.  
• Two 8-bit, back-to-back registers store data moving in both  
directions between two bidirectional buses  
• Separate Clock, Clock Enable and 3-State Enable provided for  
each register  
• 74F2952 non-inverting  
• 74F2953 inverting  
TYPICAL  
• AM2952/2953 functional equivalent  
• ‘A’ outputs sink 24mA and source 3mA  
• ‘B’ outputs sink 64mA and source 15mA  
• 300 mil wide 24-pin Slim DIP package

3. Not more than one output should be shorted at a time. For testing I , the use of high-speed test apparatus and/or sample-and-hold  
OS  
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting  
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any  
sequence of parameter tests, I tests should be performed last.
