CF5073 series

NIPPON PRECISION CIRCUITS INC.—11

SWITCHING CHARACTERISTICS

Current consumption and Output waveform with NPC’s standard crystal

FUNCTIONAL DESCRIPTION

Standby Function

When INHN goes LOW, the Q output pin becomes high impedance.

Parameter

Symbol

Conditions

1. The switching characteristics apply for normal output waveforms. Note that, depending on the matching of the CF5073 series version and crystal,

normal waveform output may not be continuous.
