DESCRIPTION
The 74ALVT162731 is a high-performance BiCMOS product designed
for V
CC
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 30
series resistance in both
the HIGH and LOW states of the output.
