General Description:
The TC426/TC427/TC428 are dual CMOS high-speed
drivers. A TTL/CMOS input voltage level is translated
into a rail-to-rail output voltage level swing. The CMOS
output is within 25 mV of ground or positive supply.
The low-impedance, high-current driver outputs swing
a 1000 pF load 18V in 30 nsec. The unique current and
voltage drive qualities make the TC426/TC427/TC428
ideal power MOSFET drivers, line drivers, and DC-toDC converter building blocks.
Applications:
•
•
•
•
8-Pin PDIP/SOIC/CERDIP
Input logic signals may equal the power supply voltage.
Input current is a low 1 A, making direct interface
to CMOS/bipolar switch-mode power supply control
ICs possible, as well as open-collector analog
comparators.
Quiescent power supply current is 8 mA maximum. The
TC426 requires 1/5 the current of the pin-compatible
bipolar DS0026 device. This is important in DC-to-DC
converter applications with power efficiency constraints
and high-frequency switch-mode power supply
applications. Quiescent current is typically 6 mA when
driving a 1000 pF load 18V at 100 kHz.
The inverting TC426 driver is pin-compatible with the
bipolar DS0026 and MMH0026 devices. The TC427 is
noninverting; the TC428 contains an inverting and noninverting driver.
Other pin compatible driver families are the TC1426/
TC1427/TC1428,
TC4426/TC4427/TC4428
and
TC4426A/TC4427A/TC4428A.

APPLICATIONS INFORMATION
3.4
3.1
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 1000 pF load to 18V in 25 nsec requires an 0.72A
current from the device power supply.
To ensure low supply impedance over a wide frequency
range, a parallel capacitor combination is recommended for supply bypassing. Low-inductance ceramic
disk capacitors with short lead lengths (< 0.5 in.) should
be used. A 1 F film capacitor in parallel with one or two
0.1 F ceramic disk capacitors normally provides
adequate bypassing.
3.2
Grounding
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.
Individual ground returns for the input and output
circuits or a ground plane should be used.
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 2.5 mA current source
load. With a logic ‘1’ input, the maximum quiescent
supply current is 8 mA. Logic ‘0’ input level signals
reduce quiescent current to 0.4 mA 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 drivers are designed with 100 mV 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 1 A over
this range.
The TC426/TC427/TC428 may be directly driven by
the TL494, SG1526/1527, SG1524, SE5560, and
similar switch-mode power supply integrated circuits.
DS21415D-page 6
Power Dissipation
The TC426/TC427/TC428 CMOS drivers have greatly
reduced quiescent DC power consumption. Maximum
quiescent current is 8 mA compared to the DS0026 40
mA specification. For a 15V supply, power dissipation
is typically 40 mW.
Two other power dissipation components are:
• Output stage AC and DC load power.
• Transition state power.
Output stage power is:
Po = PDC + PAC
= Vo (IDC) + f CL VS2
Where:
Vo
IDC
f
Vs
= DC output voltage
= DC output load current
= Switching frequency
= Supply voltage
In power MOSFET drive applications the PDC term is
negligible. MOSFET power transistors are high-impedance, capacitive input devices. In applications where
resistive loads or relays are driven, the PDC component
will normally dominate.
The magnitude of PAC is readily estimated for several
cases:

= 65 mW
1. f
2. CL
3. Vs
4. PAC
= 200 kHz
=1000 pf
= 15V
= 45 mW
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.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
