DESCRIPTION
The 74ABT2952 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT2952 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.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
