ISO7142CCDBQR

Texas Instruments · Digital Isolators · SSOP-16-150mil

ISO7142CCDBQR from Texas Instruments, in a SSOP-16-150mil. 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	VCC1	power_in	Power supply for input-side circuits, operating range 2.7 V to 5.5 V with maximum ICC of 14.5 mA at 50 Mbps.
2	GND1	power_in	Ground connection for input-side logic circuits, reference for VCCI domain.
3	INA	input	Logic input for channel A, TTL-compatible threshold VIH = 2.0 V minimum, VIL = 0.8 V maximum, input current ±10 µA.
4	INB	input	Logic input for channel B, TTL-compatible threshold VIH = 2.0 V minimum, VIL = 0.8 V maximum, input current ±10 µA.
5	OUTC	output	Isolated logic output for channel C, VOH = VCCO − 0.5 V minimum, VOL = 0.4 V maximum at IOH = 4 mA.
6	OUTD	output	Isolated logic output for channel D, VOH = VCCO − 0.5 V minimum, VOL = 0.4 V maximum at IOH = 4 mA.
7	EN1	input	Output enable input for channels A and B side, enabling outputs when high or open, high-impedance when low.
8	GND1	power_in	Ground connection for input-side logic circuits, reference for VCCI domain.
9	GND2	power_in	Ground connection for output-side logic circuits, isolated from GNDI through SiO₂ barrier.
10	EN2	input	Output enable input for channels C and D side, enabling outputs when high or open, high-impedance when low.
11	IND	input	Logic input for channel D, TTL-compatible threshold VIH = 2.0 V minimum, VIL = 0.8 V maximum, input current ±10 µA.
12	INC	input	Logic input for channel C, TTL-compatible threshold VIH = 2.0 V minimum, VIL = 0.8 V maximum, input current ±10 µA.
13	OUTB	output	Isolated logic output for channel B, VOH = VCCO − 0.5 V minimum, VOL = 0.4 V maximum at IOH = 4 mA.
14	OUTA	output	Isolated logic output for channel A, VOH = VCCO − 0.5 V minimum, VOL = 0.4 V maximum at IOH = 4 mA.
15	GND2	power_in	Ground connection for output-side logic circuits, isolated from GNDI through SiO₂ barrier.
16	VCC2	power_in	Power supply for output-side circuits, operating range 2.7 V to 5.5 V with maximum ICC of 14.5 mA at 50 Mbps.
