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 8 Channel Buffer
