No Low Voltage Terminal Required Application Zener On Chip OSC Frequency Doubling Pin Option for Smaller Output Capacitors GENERAL DESCRIPTION
Using improved design techniques and CMOS construction, the TC962 can source as much as 8mA versus the 7662’s 20mA capability. As an inverter, the TC962 can put out voltages as high as 18V and as low as 3V without the need for external diodes. Grounding this terminal will double the oscillator frequency from 12kHz to 24kHz. This will allow the use of smaller capacitors for the same output current and ripple, in most applications. Only two external capacitors are required for inverter applications. In the event an external clock is needed to drive the TC962 (such as paralleling), driving this pin directly will cause the internal oscillator to sync to the external clock.
