DESCRIPTION
The 74ALVT16953 is a high-performance BiCMOS product
designed for V
to 5V .
The 74ALVT16953 is a dual octal registered inverting transceiver.
Two 8-bit 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 (nCPXX) provided that the Clock
Enable (nCEXX
output buffers, but is only accessible when the Output Enable
(nOEXX
for B inputs to A outputs.
Active bus hold circuitry is provided to hold unused or floating data
inputs at a valid logic level.

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.
