A scientific study of the problems of digital engineering for space flight systems,
with a view to their practical solution.

SX-S Output Transients

Some sample output transient data from an RT54SX72S, L/C T25KS001, S/N LAN6701.

Functionally all outputs are low.

All pins are configured for high-slew outputs.

For PCI outputs, "hot swap" is disabled.

For TTL outputs, "hot swap" is enabled.

  abs00: PCI, pull down resistor, V_CCI only

  abs01: TTL, pull down resistor, V_CCI only

  abs02: PCI, pull down resistor, V_CCI with V_CCA applied

  abs03: TTL, pull down resistor, V_CCA with V_CCI applied

  abs04: PCI, pull up resistor, V_CCI only

  abs05: PCI, pull up resistor, V_CCI with V_CCA applied

  abs06: TTL, pull up resistor, V_CCI only

  abs07: TTL, pull up resistor, V_CCI with V_CCA applied
