TP3420A - ISDN S/T Interface Device

General Description

The TP3420A is an enhanced version of the TP3420, with a number of upgraded

Key Features

  • for compliance with the new release of ANSI T1.605-1991 and CCITT I-430. At initial power-up the device is fully backwards compatible with the TP3420 device, and modifications to the firmware are only required to take advantage of the new features. The TP3420A S Interface Device (SID™) is a complete monolithic transceiver for data transmission on twisted pair subscriber loops. It is built on National’s advanced 1.0 micron double-metal CMOS process, and requires only a single +5V supply. All func.
