LMC6008
8 Channel Buffer
General Description
The LMC6008 octal buffer is designed specifically to buffer
the multi-level voltages going to the inputs of the integrated
circuits The LMC6008 AC characteristics including settling
time are specified for a capacitive load of 0 1
mF
for this
reason
The LMC6008 contains 4 high-speed buffers and 4 low-
power buffers The high-speed buffers can provide an out-
put current of at least 250 mA (minimum) and the low-pow-
er buffers can provide at least 150 mA (minimum) By includ-
ing the 2 types of buffers the LMC6008 is able to provide
this function while consuming a supply current of only 6 5
mA (maximum) The buffers are a rail-to-rail design which
typically swing to within 30 mV of either supply
The LMC6008 also contains a standby function which puts
the buffer into a high-impedance mode The supply current
in the standby mode is a low 500
mA
max Also a thermal
limit circuit is included to protect the device from overload
conditions
