Incoming currents at pins 29 and 24 when
VCC = 5.0 V
T33A: 4 MHz, 300 mVp-p sine wave
T3A: 0.5 Vp-p video signal
T33A: time from when input went to 0 until T28A
output returned
VIN = 300 mVp-p, f = 4 MHz, output voltage
VIN = 300 mVp-p, f = 2 MHz, VDEM2
VIN = 300 mVp-p, f = 6 MHz, VDEM6
Calculate SDEM = (VDEM2 – VDEM6)/4
