† Stresses beyond those listed under "absolute maximum ratings" 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.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51-7.


Description

The SN54ALVTH162245 devices are 16-bit (dual-octal) noninverting 3-state transceivers designed for 2.5-V or 3.3-V VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

SN54ALVTH162245 can be used as two 8-bit transceivers or one 16-bit transceiver. SN54ALVTH162245 allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction control (DIR) input. The output-enable (OE) input can be used to disable the SN54ALVTH162245 so that the buses are effectively isolated.

The A-port outputs, SN54ALVTH162245 is designed to source or sink up to 12 mA, include equivalent 30- series resistors to reduce overshoot and undershoot.

SN54ALVTH162245 is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The power-up 3-state circuitry of SN54ALVTH162245 places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.

Active bus-hold circuitry of SN54ALVTH162245 is provided to hold unused or floating data inputs at a valid logic level. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.
