Holt Integrated Circuits, Inc. - Holt Integrated Circuits is a leading supplier of data bus communication ICs, primarily servicing the military, aerospace and industrial markets. Holt designs and tests all its products in-house, providing innovative, cost effective, mixed signal solutions for microprocessor-based embedded applications. Holt’s product lines include MIL-STD-1553, ARINC 429, Discrete-to-Digital sensing, Controller Area Network (CAN), analog switches and RS-485/422. Products are designed into hundreds of applications ranging from flight control and engine management to in-flight entertainment systems and test equipment.
|HI-4853H High Operating Temperature Transceivers - Holt Integrated Circuits' HI-4853H transceivers are capable of data rates up to 20 Mbps and offer extended power supply range of 3.15 V to 5.5 V, controlled slew rate, and a wide common mode voltage range (−12 V to +15 V for half-duplex, ±20 V for full-duplex). Each device delivers at least ±1.50 V and ±2.00 V output drive at worst-case supply voltages of 3.15 V and 4.5 V respectively, over an extended temperature range of −55 °C to +200 °C into a differential load of 54 Ω and 50 pF.
|HI-3000H High-Temperature CAN Transceivers - Holt Integrated Circuits' HI-3000H high-temperature transceiver family is capable of operation up to 200 °C in an 8-pin CERDIP package, and up to 175 °C in an 8-pin plastic SOIC package. The devices support two modes of operation: Normal Mode and Standby Mode. The Standby Mode is a very-low-current mode that continues to monitor bus activity, allowing the external controller to manage wake-up. Superior common-mode receiver performance makes the device especially suitable for applications where ground reference voltages may vary from point-to-point over long distances along the CAN bus.
