DESCRIPTION

The 74ALVT162731 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.

The 74ALVT162731 is designed with 30Ω series resistance in both

the HIGH and LOW states of the output.
