Frequency Control for Internal Oscillator,

FC open, fOSC =5kHz typ; FC = V+, fOSC=

50kHz typ.

FC has no effect when SYNC pin is driven

externally.

Power-Supply Ground

Input

Low-Voltage Operation Input. Tie LV to VSS

when input voltage is less than 2V. Above

2V, LV must be left open.

LV must be left open for

all input voltages

LV must be left open

for all input voltages.

SYNC

Oscillator Control Input. SYNC is connected

to an internal 15pF capacitor. An external

Oscillator may be connected to overdrive

SYNC via a 2…5nF capacitor.

SYNC shall not be connected to ground.

Same as inverter,

however, do not use

SYNC in voltage-

splitting mode
