SN75129 - 8-Channel Line Receiver

Download the SN75129 datasheet PDF. This datasheet also covers the SN75128 variant, as both devices belong to the same 8-channel line receiver family and are provided as variant models within a single manufacturer datasheet.

General Description

The SN75128 and SN75129 are eight-channel line receivers designed to satisfy the requirements of the input-output interface specification for IBM 360/370.

Both devices feature common strobes for each group of four devices.

The SN75128 has active-high strobes; the SN75129 has active-low strobes.
