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 01 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 65

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
