54LVTH162245 Datasheet | Maxwell Technologies

FEATURES : - A-Port outputs have equivalent 22-Ω series resistors, so no external resistors are required - Support mixed-mode signal operation (5V input and output voltages with 3.3V VCC) - Support unregulated battery operation down to 2.7V - Typical VOLP (output ground bounce) < 0.8V at VCC = 3.3V, TA = 25° C - IOFF and power-up 3-state support hot insertion - Bus hold on data inputs eliminates the need for external pullup/pulldown resistors - Distributed VCC and GND pin configuration minimizes highspeed switching noise - Flow-through architecture optimizes PCB layout - Total dose hardness: - > 100 krad (Si), depending upon space mission - Package: 48 pin RAD-PAK® flat pack DESCRIPTION : Maxwell Technologies’ 54LVTH162245 devices are 16-bit (dual-octal) non-inverting 3-state transceivers designed for low-voltage (3.3V) VCC 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 devices 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, which are designed to source or sink up to 12 m A, include equivalent 22-Ω series resistors to reduce overshoot and undershoot. Maxwell Technologies' patented RAD-PAK® packaging technology 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.
