LMC6008 Datasheet | National Semiconductor

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 m F 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 m A (minimum) and the low-power buffers can provide at least 150 m A (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 m A (maximum) The buffers are a rail-to-rail design which typically swing to within 30 m V 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 m A max Also a thermal limit circuit is included to protect the device from overload conditions 8 Channel Buffer Features Y Y Y Y Y High Output Current High Speed Buffers Low Power Buffers Slew Rate High Speed Buffers Low Power Buffers Settling Time CL e 0 1 m F Wide Input Output Range Supply Voltage Range Supply Current Standby Mode Current 250 m A min 150 m A min 1 7 V ms 0 85V ms 16 ms max 0 1V to VCC b 0 1V min 5V to 16V 6 5 m A max 500 m A Applications AMLCD voltage buffering Multi-voltage buffering Connection Diagram 24-Pin SO Ordering Information Package Temperature Range NSC Transport b 40 C to a 85 C Drawing Media M24B Rail Reel 24-Pin LMC6008IM Surface Mount LMC6008IMX M24B Tape TL H 12321 - 1 Top View Note Buffers 1 3 5 and 7 are High Speed and Buffers 2 4 6 and 8 are Low Speed C1996 National Semiconductor Corporation TL H 12321 RRD-B30M56 Printed in U S A Absolute Maximum Ratings (Note 1) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications ESD Tolerance (Note 2) Voltage at Input Pin Voltage at...
