6-Channel Clock Driver
Features
The EL5001 is a 6-channel level shifting driver designed
primarily for use as a clock driver in LTPS LCD displays. The
EL5001 buffers and level shifts six logic level input signals.
The six channels are grouped in to two sets, one of two
channels and one of four channels. Each set can be
configured in the inverting or non-inverting modes.
Operating from 3.3V input logic, the output swing is set using
two reference input pins. These pins can be up to 18V
differential and are not buffered, so should therefore be
bypassed effectively.
• SIx inverting/non-inverting channels
The EL5001 is designed to drive capacitive loads of 500pF
with rise and fall times of just 20ns. A three-state pin is
provided to set all outputs in to a high impedance mode. The
ENABLE pin can be used to put the device in to a power
save mode where the power consumption drops to just 3µA.
The EL5001 is available in 20-pin QFN (4mm x 4mm) and
HTSSOP packages. Both are specified for operation over
the -40°C to +85°C temperature range.
• 3.3V input logic
• 18V output
• 250µA typical supply current
• Drives up to 500pF

Applications Information
Power Dissipation Calculation
The EL5001, a six channel high performance buffer, is
directed primarily as a clock driver to LPTS LCD display
applications. The six input channels are grouped into one
group of four inputs and one group of two inputs each with a
single pin (INV1 or INV2) to toggle the polarity from inverting
to non-inverting. Each channel consists of a single Nchannel low side driver and single P-channel high side
driver. These 11Ω devices pull the output to either the high or
low voltage on VH and VL respectively, depending on the
logic input signal.
When switching at high speeds, or driving heavy loads, the
EL5001 drive capability is limited by the rise in die
temperature brought about by internal power dissipation. For
reliable operation die temperature must be kept below
TJMAX (125°C). It is necessary to calculate the power
dissipation for a given application prior to selecting package
type.
A common 3-state pin is available that when activated will
pull all 6-channel outputs to the high impedance state.
Enable and disable pins turn shutdown both inputs and
outputs. Timing plots for 3-state, enable, and disable
functions are included in the characterization
documentation.
The EL5001 is available in either a 20-pin HTSSOP or QFN
(4mm x 4mm) packages to provide a choice for power
dissipation considerations.
Supply Voltage and Input Compatibility
Power dissipation may be calculated:
4
2
2
PD = ( V S × I S ) + Σ × ( C INT × V S × f ) + ( C L × V OUT × f )
1
where:
VS = Total power supply to the EL5001 (from VS+ to VS-)
VOUT = Swing on the output (VH - VL)
CL = Load capacitance
CINT = Internal load capacitance (80pF max)
IS = Quiescent supply current (3mA max)
f = Frequency
The EL5001 is designed to operate at a maximum potential
range from 0V to 18V. Because the EL5001 does not contain
a true analog switch, the positive supply must always be 4V
higher than the negative supply.
Having obtained the application's power dissipation, the
maximum junction temperature can be calculated:
All input pins are compatible with both 3V and 5V CMOS
signals. With the positive supply set to VS = 5V the EL5001
is compatible with TTL inputs.
where:
Power Supply Bypassing
Due to the high switching currents generated by the EL5001
power supply bypassing is very important on both the
positive and negative supplies. A 4.7µF tantalum capacitor
can be used in parallel with a 0.1µF low-inductance ceramic
MLC capacitor. As with all bypass components, these should
be placed as close as possible to the supply pins. We also
recommend the VL and VH pins have some level of
bypassing especially when the device is driving highly
capacitive loads.
T JMAX = T MAX + Θ JA × PD
TJMAX = Maximum junction temperature (125°C)
TMAX = Maximum ambient operating temperature
PD = Power dissipation calculated above
θJA = Thermal resistance, junction to ambient, of the
application (package + PCB combination)
