General Description
MH88634B General Description
The Mitel MH88634-2 Central Office Interface Circuit trunk provides a complete analogue and signalling link between audio switching equipment and a telephone Line. The device is available in a single in line package for high packing densities or with a lead frame formed at 90° for low clearance applications.
The device is fabricated as a thick film hybrid incorporating various technologies for optimum circuit design and very high reliability.
This part supercedes the MH88634-2 and is pin for pin compatible.
We advise that the B rev parts are fully tested. However, we do not expect to see changes between MH88634-2 and MH88634BV-2.
The component design has been changed to improve the general performance of the part. It is also now capable of operating at a 24V battery.
