DS14C88MX

Texas Instruments · RS232 ICs · SOIC-14

DS14C88MX from Texas Instruments, in a SOIC-14. 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 V- power_in Negative supply, recommended -4.5V to -12.6V relative to GND (absolute maximum -13V).
2 INPUT A input Driver A logic input, TTL/CMOS levels with VIL max 0.8V and VIH min 2.0V.
3 OUTPUT A output Driver A EIA-232D/V.28 output with on-chip slew rate control, short-circuit current about 45 mA.
4 INPUT B1 input Driver B logic input 1, TTL/CMOS levels with VIL max 0.8V and VIH min 2.0V.
5 INPUT B2 input Driver B logic input 2, TTL/CMOS levels with VIL max 0.8V and VIH min 2.0V.
6 OUTPUT B output Driver B EIA-232D/V.28 output with on-chip slew rate control, short-circuit current about 45 mA.
7 GND power_in Ground reference (0V) for the supplies and logic inputs.
8 OUTPUT C output Driver C EIA-232D/V.28 output with on-chip slew rate control, short-circuit current about 45 mA.
9 INPUT C1 input Driver C logic input 1, TTL/CMOS levels with VIL max 0.8V and VIH min 2.0V.
10 INPUT C2 input Driver C logic input 2, TTL/CMOS levels with VIL max 0.8V and VIH min 2.0V.
11 OUTPUT D output Driver D EIA-232D/V.28 output with on-chip slew rate control, short-circuit current about 45 mA.
