ICL3222EIVZ-T

RENESAS · Pre-ordered Chips · TSSOP-20

ICL3222EIVZ-T from RENESAS, in a TSSOP-20. 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 EN input Active-low receiver enable control; driving it high places the inverting receiver outputs in high impedance (logic input threshold low max 0.8V).
2 C1+ passive External capacitor (voltage doubler) is connected to this lead.
3 V+ power_out Internally generated positive transmitter supply (+5.5V).
4 C1- passive External capacitor (voltage doubler) is connected to this lead.
5 C2+ passive External capacitor (voltage inverter) is connected to this lead.
6 C2- passive External capacitor (voltage inverter) is connected to this lead.
7 V- power_out Internally generated negative transmitter supply (-5.5V).
8 T2OUT output ±15kV ESD protected, RS-232 level (nominally ±5.5V) transmitter 2 output.
9 R2IN input ±15kV ESD protected, RS-232 compatible receiver 2 input accepting up to ±25V.
10 R2OUT output TTL/CMOS level receiver 2 output.
11 NC unconnected No connect.
12 T2IN input TTL/CMOS compatible transmitter 2 input; connect to GND if unused.
13 T1IN input TTL/CMOS compatible transmitter 1 input; connect to GND if unused.
14 NC unconnected No connect.
15 R1OUT output TTL/CMOS level receiver 1 output.
16 R1IN input ±15kV ESD protected, RS-232 compatible receiver 1 input accepting up to ±25V.
17 T1OUT output ±15kV ESD protected, RS-232 level (nominally ±5.5V) transmitter 1 output.
18 GND power_in Ground connection.
19 VCC power_in System power supply input (3.0V to 5.5V).
20 SHDN input Active-low input to shut down transmitters and on-board power supply to place the device in low-power mode.
