New Product Introduction

Renesas ISL72814SEH

INTERSIL/Renesas Electronics launches ISL72814SEH - rad-hard 16-channel current driver with integrated decoder for satellite applications

The ISL72814SEH and ISL73814SEH are radiation hardened high-voltage, high-current, driver circuit ICs fabricated using the Renesas proprietary PR40 Silicon-On-Insulator (SOI) process technology to mitigate single-event effects. The devices integrate 16 driver channels that feature a high-voltage (42V), high-current (700mA) open-emitter PNP output stage.

To further reduce solution size, the ISL72814SEH and ISL73814SEH integrate 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.
