This device translates standard TTL/ CMOS logic levels to levels conforming to EIA-232-D and CCITT V.28 standards. The device is fabricated in low threshold CMOS metal gate technology. The device provides very low power consumption compared to its bipolar equivalents: 500 µA (DS14C88) versus 25 mA (DS1488). The DS14C88 simplifies designs by eliminating the need for external slew rate control capacitors. Slew rate control in accordance with EIA-232D is provided on-chip, eliminating the output capacitors.

They are not meant to imply that the devices should be operated at these limits. The tables of “Electrical Characteristics” specify conditions for device operation. Note 2: Derate N Package 12.1 mW/˚C, and M Package 8.5 mW/˚C above +25˚C. Note 3: IOS+ and IOS− values are for one output at a time. If more than one output is shorted simultaneously, the device dissipation may be exceeded. Note 4: Power supply (V+, V−) and GND pins are connected to ground for the Output Resistance Test (RO). Note 5: AC input test waveforms for test purposes: tr = tf ≤ 20 ns, VIH = 2V, VIL = 0.8V (0.6V at V+ = 4.5V, V− = −4.5V) Note 6: Input rise and rall times must not exceed 5 µs. Note 7: The output slew rate, rise time, and fall time are measured from the +3.0V to the −3.0V level on the output waveform. Note 8: CL include jig and probe capacitances.
