Output Load
Notes:
1. Load capacitance employed depends on output type:
2. Specifications which measure delays from an active state to a High-Z state are not guaranteed by production testing, but are
characterized using 240 pF and are correlated to determine true driver turn-off time by eliminating inherent R-C delay
measurements.
3. SW1 = Open for push-pull outputs during timing test.

Derating Factor
Output timing is measured with a purely capacitive load of 50 pF or 240 pF. The following correction
factor can be used for other loads (this factor is preliminary):
A
For 3SL, MOS, TPI, AUI: CL = 50 pF
For 3SH, OCH: CL = 240 pF
SW1 = V
SW1 = GND for V
SW1 = V
SW1 = GND for High-Z to active high and active high to High-Z measurements.
= 25 C, f = 1 MHz
Derating for 3SL, MOS = -0.05 nS/pF
Derating for 3SH, OCL, TPI = -0.03 nS/pF
