TEA1067T Datasheet Low Voltage Versatile Telephone Transmission

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS DATA SHEET TEA1067 Low voltage versatile telephone transmission circuit with dialler interface Product specification File under Integrated Circuits, IC03A June 1990 Philips Semiconductors Product.

General Description

The TEA1067 is a bipolar integrated circuit performing all speech and line interface functions required in fully electronic telephone sets.

It performs electronic switching between dialling and speech.

The circuit is able to operate down to a DC line voltage of 1.6 V (with reduced performance) to facilitate the use of more telephone sets in parallel.

Key Features

  • Low DC line voltage; operates down to 1.6 V (excluding polarity guard).
  • Voltage regulator with adjustable static resistance.
  • Provides supply with limited current for external circuitry.
  • Symmetrical high-impedance inputs (64 kΩ) for dynamic, magnetic or piezoelectric microphones QUICK.
