8 Channel Buffer

LMC6008 8 Channel Buffer

April 1996

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 low­power buffers. The high-speed buffers can provide an out­put current of at least 250 mA (minimum), and the low-pow­er buffers can provide at least 150 mA (minimum). By includ­ing 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.
