54LVTH162245

1. 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.
2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
3. This current flows only when the output is in the high state and V_O > V_CC

Maxwell Technologies' 54LVTH162245 devices are 16-bit (dual-octal) non-inverting 3-state transceivers designed for
low-voltage (3.3V) V_CC operation, but with the capability to provide a TTL interface to a 5V system environment. These devices can be used as two 8-bit transceivers or one 16-bit transceiver. The 54LVTH162245 allow data transmission from the A bus to the B bus or form 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 device so that the buses are effectively isolated. The A-port outputs of 54LVTH162245, which are designed to source or sink up to 12 mA, include equivalent 22-series resistors to reduce overshoot and undershoot.

Maxwell Technologies' patented RAD-PAK^® packaging technology of 54LVTH162245 incorporates radiation shielding in the microcircuit package. It eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission. In a GEO orbit, RAD-PAK provides greater than 100 krad (Si) radiation dose tolerance. This 54LVTH162245 is available with screening up to Class S.
