characteristics enable this device

to be used in an RS-232-C inter-

face with ground loop isolation

and improved common mode

rejection. As a line receiver, the

HCPL-2300 will operate over

longer line lengths for a given

The output of the shielded inte-

grated detector circuit is an open

collector Schottky clamped tran-

sistor. The shield, which shunts

capacitively coupled common

mode noise to ground, provides a

guaranteed transient immunity

specification of 100 V/

µs. The

output circuit includes an

optional integrated 1000

Ω pull-

up resistor for the open collector.

This gives designers the flexibility

to use the internal resistor for

pull-up to five volt logic or to use

an external resistor for connec-

tion to supply voltages up to 18 V

(CMOS logic voltage).

The Electrical and Switching

Characteristics of the HCPL-2300

are guaranteed over a tempera-

ture range of -40

°C to 85°C. This

enables the user to confidently

design a circuit which will

operate under a broad range of

operating conditions.
