Additional Details

The MD82C86H-5/B operates from a single 5V power supply. The enable input controls the direction of data flow through the transceiver. It is typically packaged in a DIP (Dual In-Line Package) or SOIC (Small Outline Integrated Circuit) package. The operating temperature range is typically from -55°C to +125°C for the high-reliability versions. The device includes internal pull-up resistors on the enable inputs to prevent floating inputs. The output drive capability is sufficient to drive multiple TTL loads.
