Note 7: Voltage Range 5.0V
± 0.5V
Note 8: Timing pertains to the TYPE1 BSR and TYPE2 BSR after the buffer (BSR 0–8, 9–17, 18–26, 27–35, 36–44, 45–53, 54–62, 63–71).
Note 9: Timing pertains to BSR 74 and 78 only.
Note 10: Timing pertains to BSR 75 and 79 only.
Note 11: Timing pertains to BSR 72, 73, 76 and 77 only.
Note: All Input Timing Delays involving TCK are measured from the rising edge of TCK.
Capacitance
Note 12: CI/O is measured at frequency f = 1 MHz, per MIL-STD-883B, Method 3012.
