The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. The detailed block diagram and the pin-out of the ASIC are shown in Figure 1 and Table 1. Figure 1. Detailed Block Diagram of TRF1216 TERMINAL FUNCTIONS TERMINAL I/O TYPE DESCRIPTION NO.
