Notes
1. All S/UNI-JET inputs and bi-directionals present minimum capacitive loading and operate at TTL logic
levels.
2. All S/UNI-JET outputs and bi-directionals have at least 3 mA drive capability. The data bus outputs,
D[7:0], have 3 mA drive capability. The FIFO interface outputs, RDAT[15:0], RPRTY, RCA, DRCA,
RSOC, TCA, and DTCA, have 12 mA drive capability. The outputs TCLK, TPOS/TDATO, TNEG/TOHM,
TPOHFP/TFPO/TMFPO/TGAPCLK, LCD/RDATO, RPOH/ROVRHD, RPOHCLK/RSCLK/RGAPCLK,
and REF8KO/RPOHFP/RFPO/RMFPO have 6 mA drive capability. All other outputs have 3 mA drive
capability.
3. Inputs RSTB, ALE, TMS, TDI, and TRSTB have internal pull-up resistors.
4. RSTB, TRSTB, TMS, TDI, TCK, REF8KI, TFCLK, RFCLK, TICLK, and RCLK are schmitt trigger input
pads.
5. The VSS [59:1] ground pins are not internally connected together. Failure to connect these pins
externally may cause malfunction or damage the S/UNI-JET.
6. The VDD[32:1] power pins are not internally connected together. Failure to connect these pins
externally may cause malfunction or damage the device. These power supply connections must all be
used and must all connect to a common +3.3 V or ground rail, as appropriate.
7. During power-up and power-down, the voltage on the BIAS pin must be kept equal to or greater than
the voltage on the VDD [32:1] pins, to avoid damage to the device.
