ISO7240CFDWR

Texas Instruments · Digital Isolators · SOIC-16-300mil

ISO7240CFDWR from Texas Instruments, 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 VCC1 power_in Power supply voltage for input side channels, rated 3.15V to 5.5V.
2 GND1 power_in Ground connection for VCC1 input side.
3 INA input Input signal for channel A; accepts 0V to VCC + 0.5V with TTL threshold approximately 1.5V.
4 INB input Input signal for channel B; accepts 0V to VCC + 0.5V with TTL threshold approximately 1.5V.
5 INC input Input signal for channel C; accepts 0V to VCC + 0.5V with TTL threshold approximately 1.5V.
6 IND input Input signal for channel D; accepts 0V to VCC + 0.5V with TTL threshold approximately 1.5V.
7 DISABLE input Input disable control; when high disables all input pins, when low or open enables all input pins; accepts 0V to 5.5V.
8 GND1 power_in Ground connection for VCC1 input side.
9 GND2 power_in Ground connection for VCC2 output side.
10 CTRL input Fail-safe output control pin; determines output state when DISABLE is high or VCC1 is powered down; high or open produces high output, low produces low output.
11 OUTD output Output signal for channel D; provides galvanically isolated version of IND signal with ±4mA drive capability.
12 OUTC output Output signal for channel C; provides galvanically isolated version of INC signal with ±4mA drive capability.
13 OUTB output Output signal for channel B; provides galvanically isolated version of INB signal with ±4mA drive capability.
14 OUTA output Output signal for channel A; provides galvanically isolated version of INA signal with ±4mA drive capability.
15 GND2 power_in Ground connection for VCC2 output side.
16 VCC2 power_in Power supply voltage for output side channels, rated 3.15V to 5.5V.
