P T = fV s ( 10 × 10 )
A resistive-load-caused dissipation for supply-
referenced loads is a function of duty cycle, load
current and output voltage. The power dissipation is

D = Duty Cycle

Quiescent power dissipation depends on input signal
duty cycle. Logic HIGH outputs result in a lower power

dissipation mode, with only 0.6 mA total current drain
(all devices driven). Logic LOW outputs raise the
current to 4 mA maximum. The quiescent power
dissipation is:
EQUATION
P Q = V S ( D ( I H ) + ( 1 – D ) I L )
I H = Quiescent Current with all outputs LOW
(4 mA max.)
I L = Quiescent Current with all outputs HIGH
(0.6 mA max.)
D = Duty Cycle
Package power dissipation is the sum of load,
quiescent and transition power dissipations. An
example shows the relative magnitude for each term:
Maximum operating temperature is:
EQUATION
T J – θ JA ( P D ) = 141 ° C
T J = Maximum allowable junction temperature
(+150 ° C )
θ JA = Junction-to-ambient thernal resistance

V S = Supply Voltage
Transition power dissipation arises in the complimen-
tary configuration (TC446X) because the output stage
N-channel and P-channel MOS transistors are ON
simultaneously for a very short period when the output
changes. The transition power dissipation is
approximately:
V DD
Note:
Ambient operating temperature should not
exceed +85°C for "EJD" device or +125°C
for "MJD" device.
