Description
The 74ALVT16731 is a high-performance BiCMOS product designed for VCC operation at 2.5V to 3.3V with I/O
compatibility up to 5V.
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.
