DESCRIPTION
The LVT2952 is a high-performance BiCMOS product designed for
V
This device combines low static and dynamic power dissipation with
high speed and high output drive.
The 74LVT2952 device is an 8-bit registered 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.
