Individual RS-485/422 transceivers are tailored towards specific application needs. Features include high operating temperature (up to 200^oC), controlled slew rate for optimum EMI performance, full-duplex or half-duplex and high or low speed versions.

Holt offers a range of analog switches which are available in numerous configurations, including single-pole/single-throw (SPST), normally open (NO), normally closed (NC) or a combination of NO and NC. The devices are fabricated on a robust silicon-on-insulator (SOI) technology resulting in latch-up free operation and low off-state leakage. This makes these devices ideal for applications that benefit from or require low charge injection, high isolation or low leakage, such as sample and hold and other precision multiplexers. Select products are capable of higher operating temperatures (up to 200^oC).

Holt has leveraged its expertise in providing mixed signal ARINC 429 and MIL-STD-1553 solutions and produced the first ARINC 825 compliant CAN controller with an integrated transceiver. All CAN devices are capable of interfacing with digital logic from 2.5V to 5V and operating in the temperature range -55^oC to +125^oC. Select transceiver products are capable of higher operating temperatures (up to 200^oC). Additional attractive features include deep FIFOs, a flexible frame filtering scheme tailored to ARINC 825 applications, short-circuit survival to +/- 58V and the smallest footprint protocol/transceiver combination available.

Holt also offers Protocol Bridge ICs, allowing easy communication between ARINC 429 and ARINC 825 (CAN) buses. The HI-3200 can be programmed to automatically re-format, re-label, re-packetize and retransmit data from ARINC 429 receive buses to ARINC 429 transmit buses, as well as from ARINC 429 to ARINC 825 (CAN) or the other way around.  See also our ARINC 429 data management/bridge products here.

All CAN Controllers have been independently validated according to protocol specification ISO 11898 and test specification ISO 16845 by C&S group, GmbH. The validation report is available on request.

Holt Integrated Circuits line of LCD Display Drivers are designed for high voltage LCD display drive applications. These CMOS products drive the liquid crystal displays by converting 5 volt serial data to parallel segment and backplane waveforms with amplitudes up to 30 volts. Devices are cascadable, allowing connection of multiple drivers for larger displays.
