The ISL72814SEHEV1Z evaluation board features the ISL72814SEH 16-channel driver circuit IC. The IC is a radiation hardened, high-voltage, high-current, 16-channel driver circuit with an integrated decoder for driving and selecting between a bank of relays, waveguide and coaxial switches in space applications. The ISL72814SEHEV1Z is fabricated using the Renesas proprietary PR40 silicon-on-insulator process (SOI) technology to mitigate single-event effects. It integrates 16 current drivers that feature high-voltage (42V), high-current (700mA) open-emitter positive-negative-positive (PNP) and common collector output stage.
To further reduce solution size, the ISL72814SEH integrates a 4-bit, 16-channel decoder with Enable. This conveniently allows you to select 1 of 16 available driver channels or disable all channels. The inputs to the decoder are TTL and CMOS compatible, allowing an easy interface to FPGAs and microprocessors.
The ISL7x814SEH devices operate across the military temperature range from -55 °C to +125 °C and are available in a 28-lead hermetically sealed ceramic dual flatpack (CDFP) package or die.
