This pin driver has improved performance over existing pin drivers. It
is specifically designed to operate at voltages down to 0V across the
switch elements while maintaining good speed and on-resistance
characteristics.
Available in the 8-Pin SOIC and 8-Pin PDIP packages, the EL7155C
is specified for operation over the -40°C to +85°C temperature range.
Ordering Information
Part No.
Output pins OUTH and OUTL are connected to input pins VH and VL
respectively, depending on the status of the IN pin. One of the output
pins is always in tri-state, except when the OE pin is active low, in
which case both outputs are in tri-state mode. The isolation of the output FETs from the power supplies enables VH and VL to be set
independently, enabling level-shifting to be implemented.

Application Information
Product Description
The EL7155C is available in both the 8-pin SOIC and
the 8-pin PDIP packages. The relevant package should
b e c h o se n de p en d i n g o n t h e c al cu l a t e d p ow er
dissipation.
The EL7155C is a high performance 40MHz pin driver.
It contains two analog switches connecting VH to
OUTH and VL to OUTL. Depending on the value of the
IN pin, one of the two switches will be closed and the
other switch open. An output enable (OE) is also supplied which opens both switches simultaneously.
Supply Voltage Range and Input Compatibility
The EL7155C is designed for operation on supplies from
5V to 15V (4.5V to 18V maximum). The table on page 6
shows the specifications for the relationship between the
VS+, VH, VL, and GND pins.
Due to the topology of the EL7155C, VL should always
be connected to a voltage equal to, or lower than GND.
VH can be connected to any voltage between VL and the
positive supply, VS+.
All input pins are compatible with both 3V and 5V
CMOS signals. With a positive supply (VS+) of 5V, the
EL7155C is also compatible with TTL inputs.

Power Supply Bypassing
• IS is the quiescent supply current (3mA max.) and
When using the EL7155C, it is very important to use
adequate power supply bypassing. The high switching
currents developed by the EL7155C necessitate the use
of a bypass capacitor between the VS+ and GND pins. It
is recommended that a 2.2µF tantalum capacitor be used
in parallel with a 0.1µ F low-inductance ceramic MLC
capacitor. These should be placed as close to the supply
pins as possible. It is also recommended that the VH and
VL pins have some level of bypassing, especially if the
EL7155C is driving highly capacitive loads.
• f is frequency
Having obtained the application’s power dissipation, a
maximum package thermal coefficient may be determined, to maintain the internal die temperature below
Tjmax:
( T jmax – T max )
θ ja = ------------------------------------PD
where:
• Tjmax is the maximum junction temperature (125°C),
Power Dissipation Calculation
• Tmax is the maximum operating temperature,
When switching at high speeds, or driving heavy loads,
the EL7155C 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 the package type.
• PD is the power dissipation calculated above,
• θja thermal resistance on junction to ambient.
θja is 160°C/W for the SO8 package and 100°C/W for
the PDIP8 package when using a standard JEDEC
JESD51-3 single-layer test board. If Tjmax is greater than
125°C when calculated using the equation above, then
one of the following actions must be taken:
Power dissipation may be calculated:
2
2
PD = ( V S × I S ) + ( C INT × V S × f ) + ( C L × V OU T × f )
• Reduce θja the system by designing more heat-sinking
into the PCB (as compared to the standard JEDEC
JESD51-3)
where:
• VS is the total power supply to the EL7155C (from
VS+ to GND),
• Use the PDIP8 instead of the SO8 package
• De-rate the application either by reducing the switching frequency, the capacitive load, or the maximum
operating (ambient) temperature (Tmax)
• Vout is the swing on the output (VH - VL),
• CL is the load capacitance,
• CINT is the internal load capacitance (50pF max.),
