HT3232ARZ

HTCSEMI · Buffer/Driver/Transceiver · SOIC-16

HT3232ARZ from HTCSEMI, in a SOIC-16. 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 C1+ passive Positive terminal for the first charge-pump flying capacitor C1 (0.1 µF typical). Works with C1- to generate the doubled V+ rail.
2 V+ power_out Doubled voltage output from the charge pump (approximately 2 × VCC). Requires a 0.1 µF reservoir capacitor to GND. Absolute max (VCC − 0.3) to 7 V.
3 C1- passive Negative terminal for the first charge-pump flying capacitor C1 (0.1 µF typical).
4 C2+ passive Positive terminal for the second charge-pump flying capacitor C2 (0.1 µF typical). Works with C2- to generate the inverted V- rail.
5 C2- passive Negative terminal for the second charge-pump flying capacitor C2 (0.1 µF typical).
6 V- power_out Inverted (negative) charge-pump output, approximately −VCC. Requires a 0.1 µF reservoir capacitor to GND. Absolute range 0.3 to -7 V.
7 T2OUT output Second transmitter RS-232 output. Drives the RS-232 line to ±5.4 V typical at VCC = 5.0 V (±4.0 V at VCC = 3.3 V) into a 3 kΩ load. Short-circuit current limited to ±60 mA.
8 R2IN input Second receiver RS-232 input. Accepts ±25 V RS-232 line signals. Input resistance 3-7 kΩ (5 kΩ typ), thresholds VIL ≥ 0.6 V and VIH ≤ 2.4 V, hysteresis 0.3 V typ.
9 R2OUT output Second receiver TTL/CMOS output. Drives logic-level output from the RS-232 input; VOL ≤ 0.4 V at 1.6 mA (VCC = 3.3 V), VOH ≥ VCC − 0.6 V at −0.5 mA.
10 T2IN input Second transmitter TTL/CMOS input. Logic-level input driving the RS-232 transmitter. VIL ≤ 0.8 V, VIH ≥ 2.0 V (VCC = 3.3 V), 250 mV typical hysteresis, ±1 µA max leakage.
11 T1IN input First transmitter TTL/CMOS input. Logic-level input driving the RS-232 transmitter. VIL ≤ 0.8 V, VIH ≥ 2.0 V (VCC = 3.3 V), 250 mV typical hysteresis.
12 R1OUT output First receiver TTL/CMOS output. Drives logic-level output from the RS-232 input; VOL ≤ 0.4 V at 1.6 mA (VCC = 3.3 V), VOH ≥ VCC − 0.6 V at −0.5 mA.
13 R1IN input First receiver RS-232 input. Accepts ±25 V RS-232 line signals. Input resistance 3-7 kΩ (5 kΩ typ), thresholds VIL ≥ 0.6 V and VIH ≤ 2.4 V.
14 T1OUT output First transmitter RS-232 output. Drives the RS-232 line to ±5.4 V typical at VCC = 5.0 V (±4.0 V at VCC = 3.3 V) into a 3 kΩ load. Short-circuit current limited to ±60 mA.
15 GND power_in Device ground reference. Common return for the supply, charge-pump capacitors and RS-232 signalling.
16 VCC power_in Positive supply input, 3.0 V to 5.5 V (nominal 3.3 V or 5 V). Requires a 0.1 µF bypass capacitor to GND. ISUPPLY ≈ 2.5 mA typ at 3.3 V, 6 mA typ at 5 V (no load). Absolute max −0.3 to 6 V.
