|
| 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 |
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 mA, include equivalent 22-. series resistors to reduce overshoot and undershoot.
About RAD-PAK® Technology
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. This product is available with screening up to Class S.
