54LVTH162244 Octal Driver/Buffer, 16-bit, 3.3V				54LVTH162244 Information - Product Datasheet - Product Flow - Back to Logic

Features

• RAD-PAK® radiation-hardened against natural space radiation
• Total dose hardness:
  • > 100 krad (Si), depending upon space mission
• Output ports have equivalent 22-. 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 pull-up/pull-down resistors
• Distributed VCC and GND pin configuration minimizes highspeed switching noise
• Flow-through architecture optimizes PCB layout
• Package:
  • 48 pin RAD-PAK flat pack

Description

Maxwell Technologies’ 54LVTH162244 devices are 16-bit buffers and line drivers 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 four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetrical active-low output-enable (OE) inputs. The outputs, which are designed to source or sink up to 12 mA, include equivalent 22-. series resistors to reduce overshoot and undershoot. Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

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.
