3.1  
APPLICATIONS INFORMATION  
Supply Bypassing  
The supply current vs frequency and supply current  
vs capacitive load characteristic curves will aid in  
determining power dissipation calculations.  
Charging and discharging large capacitive loads  
quickly requires large currents. For example, charging  
a 1000pF load to 18V in 25nsec requires an 0.72A  
current from the device power supply.  
The TC426/TC427/TC428 CMOS drivers have greatly  
reduced quiescent DC power consumption. Maximum  
quiescent current is 8mA compared to the DS0026  
40mA specification. For  
dissipation is typically 40mW.  
a 15V supply, power  
To ensure low supply impedance over a wide frequency  
range, a parallel capacitor combination is recom-  
mended for supply bypassing. Low-inductance ceramic  
disk capacitors with short lead lengths (< 0.5 in.) should  
be used. A 1µF film capacitor in parallel with one or two  
0.1µF ceramic disk capacitors normally provides  
adequate bypassing.  
Two other power dissipation components are:  
• Output stage AC and DC load power.  
• Transition state power.  
Output stage power is:  
Po = PDC + PAC  
3.2  
Grounding  
2
= Vo (IDC) + f CL VS  
The TC426 and TC428 contain inverting drivers.  
Ground potential drops developed in common ground  
impedances from input to output will appear as  
negative feedback and degrade switching speed  
characteristics.  
Where:  
Vo = DC output voltage  
IDC = DC output load current  
f
= Switching frequency  
Individual ground returns for the input and output  
circuits or a ground plane should be used.  
Vs = Supply voltage  
In power MOSFET drive applications the PDC term is  
negligible. MOSFET power transistors are high imped-  
ance, capacitive input devices. In applications where  
resistive loads or relays are driven, the PDC component  
will normally dominate.  
3.3  
Input Stage  
The input voltage level changes the no-load or  
quiescent supply current. The N-channel MOSFET  
input stage transistor drives a 2.5mA current source  
load. With a logic "1" input, the maximum quiescent  
supply current is 8mA. Logic "0" input level signals  
reduce quiescent current to 0.4mA maximum.  
Minimum power dissipation occurs for logic "0" inputs  
for the TC426/TC427/TC428. Unused driver inputs  
must be connected to VDD or GND.  
The magnitude of PAC is readily estimated for several  
cases:  
A.  
B.  
1. f  
= 200kHZ  
1. f  
= 200kHz  
2. CL =1000pf  
3. Vs = 18V  
2. CL =1000pf  
3. Vs = 15V  
The drivers are designed with 100mV of hysteresis.  
This provides clean transitions and minimizes output  
stage current spiking when changing states. Input  
voltage thresholds are approximately 1.5V, making the  
device TTL compatible over the 4.5V to 18V supply  
operating range. Input current is less than 1µA over this  
range.  
4. PAC = 65mW  
4. PAC = 45mW  
During output level state changes, a current surge will  
flow through the series connected N and P channel  
output MOSFETS as one device is turning "ON" while  
the other is turning "OFF". The current spike flows only  
during output transitions. The input levels should not be  
maintained between the logic "0" and logic "1" levels.  
Unused driver inputs must be tied to ground and  
not be allowed to float. Average power dissipation will  
be reduced by minimizing input rise times. As shown in  
the characteristic curves, average supply current is  
frequency dependent.  
The TC426/TC427/TC428 may be directly driven by  
the TL494, SG1526/1527, SG1524, SE5560, and  
similar switch-mode power supply integrated circuits.
