APPLICATION INFORMATION
latch-up avoidance
Because CMOS devices are susceptible to latch-up due to their inherent parasitic thyristors, the TLC220x,
TLC220xA, and TLC220xB inputs and outputs are designed to withstand –100-mA surge currents without
sustaining latch-up; however, techniques reducing the chance of latch-up should be used whenever possible.
Internal protection diodes should not be forward biased in normal operation. Applied input and output voltages
should not exceed the supply voltage by more than 300 mV. Care should be exercised when using capacitive
coupling on pulse generators. Supply transients should be shunted by the use of decoupling capacitors
(0.1
μ
F typical) located across the supply rails as close to the device as possible.
electrostatic discharge protection
These devices use internal ESD-protection circuits that prevent functional failures at voltages at or below
2000 V. Care should be exercised in handling these devices as exposure to ESD may result in degradation of
the device parametric performance.
macromodel information
Macromodel information provided was derived using Microsim Parts
, the model generation software used
with Microsim PSpice
. The Boyle macromodel (see Note 5) and subcircuit in Figure 40 were generated using
the TLC220x typical electrical and operating characteristics at 25
°
C. Using this information, output simulations
of the following key parameters can be generated to a tolerance of 20% (in most cases):
Maximum positive output voltage swing
Maximum negative output voltage swing
Slew rate
Quiescent power dissipation
Input bias current
Open-loop voltage amplification
