S5935 – PCI Product
Synchronous RD# FIFO Timing
Functional Operation Range (VCC=5.0V 5%, 0 C to 70 C T 50 pf load on outputs).
Notes:
1. Data is valid for 22ns for a 31ns t 124 RD# Setup.
2. RD# and SELECT# must both be asserted to dric=ve DQ[31:0] - delay is from the last one asserted.
3. When increasing Setup times, ADR[6:2], BE[3:0]#, SELECT#, and RD# timing relations remain relative to each other as shown.
4. Min and Max are indicated to allow increased valid data time as shown by dashed lines. First accesses are async.
