DESCRIPTION
The 74ALVT16731 is a high-performance BiCMOS product designed
for V
operation at 2.5V to 3.3V with I/O compatibility up to 5V.
CC
This device is a 1-to-4 address register/driver featuring non-inverting
3-State outputs. The state of the outputs are controlled by two
enable inputs (OE1 and OE2). Each enable input controls the state
of two of the four common outputs for each input. When an OEn
input is a logic High, the respective outputs will be in the high
impedance state. When an OEn input is a logic Low, the respective
outputs are active. The device can be configured for a transparent
mode from input to output or a register mode by the SEL input.
When SEL is a logic High the device is configured for transparent
mode and when SEL is a logic Low it is configured for register
mode. While in the register mode the output follows the input on the
rising edge of the CLK input. The function of the data registers is not
effected by either SEL or OEn.

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 negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
