DS14C88 QUAD CMOS Line Driver General Description The DS14C88, pin-for-pin compatible to the DS1488/ MC1488, is a quad line drivers designed to interface data terminal equipment (DTE) with data circuit-terminating equipment (DCE). 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.
