CF5014 series

NIPPON PRECISION CIRCUITS INC.—7

FUNCTIONAL DESCRIPTION

Standby Function

When INHN goes LOW, the oscillator stops and the oscillator output on Q becomes high impedance.

Power-save Pull-up Resistance

The INHN pull-up resistance changes in response to the input level (HIGH or LOW). When INHN goes LOW

(standby state), the pull-up resistance becomes large to reduce the current consumption during standby.
