CA-IS3761HW from Chipanalog, in a SOIC-16-300mil. 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 VDDA power_in A-side supply voltage, recommended 2.375 V to 5.5 V with an absolute maximum of 6.0 V, referenced to GNDA.
2 VI1 input A-side forward logic input with Schmitt-trigger thresholds, VIH minimum 2.0 V and VIL maximum 0.8 V.
3 VI2 input A-side forward logic input with Schmitt-trigger thresholds, VIH minimum 2.0 V and VIL maximum 0.8 V.
4 VI3 input A-side forward logic input with Schmitt-trigger thresholds, VIH minimum 2.0 V and VIL maximum 0.8 V.
5 VI4 input A-side forward logic input with Schmitt-trigger thresholds, VIH minimum 2.0 V and VIL maximum 0.8 V.
6 VI5 input A-side forward logic input with Schmitt-trigger thresholds, VIH minimum 2.0 V and VIL maximum 0.8 V.
7 VO6 output A-side reverse-channel logic output, rail-to-rail with about 50 Ω output impedance; it takes the default-high state (CA-IS376xH) when the input-side supply is lost.
8 GNDA power_in A-side ground reference point; all voltages on the A side are referenced to this pin.
9 GNDB power_in B-side ground reference point; all voltages on the B side are referenced to this pin.
10 VI6 input B-side reverse-channel logic input with Schmitt-trigger thresholds, VIH minimum 2.0 V and VIL maximum 0.8 V.
11 VO5 output B-side forward-channel logic output, rail-to-rail with about 50 Ω output impedance.
12 VO4 output B-side forward-channel logic output, rail-to-rail with about 50 Ω output impedance.
13 VO3 output B-side forward-channel logic output, rail-to-rail with about 50 Ω output impedance.
14 VO2 output B-side forward-channel logic output, rail-to-rail with about 50 Ω output impedance.
15 VO1 output B-side forward-channel logic output, rail-to-rail with about 50 Ω output impedance.
16 VDDB power_in B-side supply voltage, recommended 2.375 V to 5.5 V with an absolute maximum of 6.0 V, referenced to GNDB.
