SN75207B - DUAL SENSE AMPLIFIER

Description

The SN75207B is a terminal-for-terminal replacement for the SN75107B.

The improved input sensitivity makes it more suitable for MOS memory sense amplifiers and can result in faster memory cycles.

Features

  • a TTL-compatible, active-pullup output. Input protection diodes are in series with the collectors of the differential-input transistors of the SN75207B. These diodes are useful in certain party-line systems that may have multiple VCC + power supplies and may be operated with some of the VCC + supplies turned off. In such a system, if a supply is turned off and allowed to go to ground, the equivalent input circuit connected to that supply would be as follows: Input SN75207B This would be a prob.
