Overview
Description
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.

When the ISL72814SEH or ISL73814SEH are driving inductive loads do I need additional external protection?
Question: When driving inductive loads do I need additional external protection? Answer: No, these parts offer clamp diodes on each of their 16 output channels to the COM pin. This allows the COM pin to suppress in the inductive transient voltage generated when a channel is driving an inductive load.

When using the ISL72814SEH or ISL73814SEH can more than one output be enabled at the same time?
Question: Can more than one output be enabled at the same time? Answer: No, only a single output can be enabled by using the address lines A0-A3 and the Enable input. You can cross-strap two devices to the same load to provide more current. An example of cross ...

Is the ISL73814SEH the same as the ISL72814SEH?
Question: Are these two parts the same? Answer: Yes, they are the same design. The only difference is that the ISL73814SEH is only wafer acceptance tested to 75krad(Si) over the low dose rate of 10mrad(Si)/s but it does have the same single event effects rating at ...
