HT339ARQZ

HTCSEMI · Comparators · QFN16(3x3)

HT339ARQZ from HTCSEMI, in a QFN16(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC+ power_in Positive supply; single supply 3.0 V to 36 V (split supply ±1.5 V to ±18 V).
2 IN-1 input Inverting input of comparator 1; common-mode range 0 to VCC-1.5 V, keep input resistors <10 kΩ.
3 NC unconnected No internal connection.
4 IN+1 input Non-inverting input of comparator 1; common-mode range 0 to VCC-1.5 V, ground if unused.
5 IN-2 input Inverting input of comparator 2; common-mode range 0 to VCC-1.5 V, ground if unused.
6 IN+2 input Non-inverting input of comparator 2; common-mode range 0 to VCC-1.5 V, ground if unused.
7 IN-3 input Inverting input of comparator 3; common-mode range 0 to VCC-1.5 V, ground if unused.
8 IN+3 input Non-inverting input of comparator 3; common-mode range 0 to VCC-1.5 V, ground if unused.
9 IN-4 input Inverting input of comparator 4; common-mode range 0 to VCC-1.5 V, ground if unused.
10 NC unconnected No internal connection.
11 IN+4 input Non-inverting input of comparator 4; common-mode range 0 to VCC-1.5 V, ground if unused.
12 VCC- power_in Negative supply / ground (GND in the 14-pin packages); ground for single-supply operation.
13 OUT4 output Open-collector output of comparator 4; sinks 16 mA typ (6 mA min) with 130 mV typ saturation at 4 mA.
14 OUT3 output Open-collector output of comparator 3; sinks 16 mA typ (6 mA min) with 130 mV typ saturation at 4 mA.
15 OUT2 output Open-collector output of comparator 2; sinks 16 mA typ (6 mA min) with 130 mV typ saturation at 4 mA.
16 OUT1 output Open-collector output of comparator 1; sinks 16 mA typ (6 mA min) with 130 mV typ saturation at 4 mA.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
