SNOS970D – JUNE 2001 – REVISED NOVEMBER 2014

5 Description (continued)

In portable applications, the LMH6647 provides shutdown capability while keeping the turn-off current to less

than 50

μA. Both turn-on and turn-off characteristics are well behaved with minimal output fluctuations during

transitions. This allows the part to be used in power saving mode, as well as multiplexing applications. Miniature

packages (SOT-23, VSSOP-8, and SOIC-8) are further means to ease the adoption of these low power high

speed devices in applications where board area is at a premium.
