HT7660ARZ

HTCSEMI · Translators, Level Shifters · SOP-8

HT7660ARZ from HTCSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No Connection
2 CAP+ passive Pump capacitor (C1) positive terminal; connect positive lead of 10μF capacitor for charge pump operation
3 GND power_in Ground reference
4 CAP-V passive Output filter capacitor (C2) positive terminal; connect positive lead of 10μF capacitor for output voltage filtering and ripple reduction
5 OUT output Negative voltage output with typical source resistance of 100Ω at 20mA load current, maximum 120Ω from 0°C to 70°C
6 LV input Low voltage mode control input; tie to GND for V+ <3.5V, leave floating for V+ >3.5V to prevent latchup; input voltage range -0.3V to (V+ +0.3V)
7 OSC input Oscillator frequency control input; nominal frequency 10kHz at V+ =5V, externally adjustable via external capacitor or external clock with 1kΩ series resistor
8 V+ power_in Positive supply voltage input with operating range 1.5V to 12.0V for HT7660A variant, absolute maximum rating 13.0V
