Notes

All S/UNI-JET inputs and bi-directionals present minimum capacitive loading and operate at TTL logic

levels.

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.

Inputs RSTB, ALE, TMS, TDI, and TRSTB have internal pull-up resistors.

RSTB, TRSTB, TMS, TDI, TCK, REF8KI, TFCLK, RFCLK, TICLK, and RCLK are schmitt trigger input

pads.

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.

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.

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.
