AC Test Load Circuits
BUSY, CBRQ LOAD CIRCUIT
AEN LOAD CIRCUIT
BPRO, BREQ LOAD CIRCUIT
NOTE: Includes Stray and Jig Capacitance
AC Testing Input, Output Waveform
AC Testing: Inputs are driven at VIH +0.4V for a logic “1” and VIL
-0.4V for a logic “0”. The clock is driven at VCC -0.4V and 0.4V. Tim-
ing measurements are made at 1.5V for both a logic “1” and “0”.
