General Description
The EL2003C and EL2033C are general purpose monolithic unity
gain buffers featuring 100MHz, -3dB bandwidth and 4ns small signal
rise time. These buffers are capable of delivering a 100mA current to
a resistive load and are oscillation free into capacitive loads. In addi-
tion, the EL2003C and EL2033C have internal output short circuit
current limiting which will protect the devices under both a DC fault
condition and AC operation with reactive loads. The extremely fast
slew rate of 1200V/ s, wide bandwidth, and high output drive make
the EL2003C and EL2033C ideal choices for closed loop buffer appli-
cations with wide band op amps. These same characteristics and
excellent DC performance make the EL2003C and EL2033C excellent
choices for open loop applications such as driving coaxial and twisted
pair cables.
The EL2003C and EL2033C are constructed using Elantec's propri-
etary dielectric isolation process that produces PNP and NPN
transistors with essentially identical AC and DC characteristics.

Power Dissipation
See Curves
The maximum power dissipation depends on package type, ambient temperature and
heat sinking. See the characteristic curves for more details.
Output Short Circuit Duration
Continuous
A heat sink is required to keep the junction temperature below the absolute maximum
when the output is short circuited.
