VeG must be applied simultaneously or ~fore Vpp and removed simultaneously.or after Vpp. The ETC 2732 must not be inser·ted Into or removed from a board with Vpp at 25 ± 1 V to prevent damage to. the device.2. The maximum allowable voltage which may be applied to the Vpp pin during programming is 26V. Care must be taken whenswitching the Vpp supply to prevent overshoot exceeding this 26V maximum specification. A 0.1. ~F capac"or is required acrossVpp, Vee to GND to suppress spurious voltage transients which may damage the device.8/10.108
