Product Brief

June 2000

L7581/2/3 and L8581

Ringing, Tip/Ring, and Line Card Access Switches

Features

Description

The L7581/8581 provides solid-state access for

power ringing applications. The L7582 provides

access for power ringing and line test. The L7583

line card access switch (LCAS) provides power ring-

ing, line test, and self-test access.

Incorporated into the L758xA is a diode bridge/SCR

clamping circuit, current-limiting circuitry, and thermal

shutdown mechanism. The L758xB provides a diode

bridge clamping circuit, current-limiting circuitry, and

thermal shutdown mechanism.

A single external protection device is required. Agere

Systems Inc. has available characterized protection

devices designed to work with Agere LCAS devices

(contact a Agere account representative for informa-

tion about these products).

Agere LCAS devices require a 5 V supply to operate.

Additionally, a battery monitor circuit is included,

which forces an all-off state if the battery is lost.

The L7581 device is packaged in a 16-pin, plastic

DIP package (L7581AC/BC) and a 16-pin, plastic

SOG package (L7581AAE/BAE). These devices are

pin compatible with the L7541 device.

The L7582 device is packaged in a 16-pin, plastic

DIP package (L7582AC/BC) and a 16-pin,

plastic SOG package (L7582AAE/BAE). The

L7582AAE/BAE are pin compatible with the

L7542AAE/BAE.

The L7583A/B/C/D device is packaged in a 24-pin,

plastic DIP (L7583AF/BF/CF/DF) and a 28-pin,

plastic SOG package (L7583AAJ/BAJ/CAJ/DAJ).
