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 consump-

tion 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 ac-

cordance with EIA-232D is provided on-chip, eliminating the

output capacitors.
