SN75138 Overview
Description
The SN55138 and SN75138 quadruple bus transceivers are designed for two-way data communication over single-ended transmission lines. Each of the four identical channels consists of a driver with TTL inputs and a receiver with a TTL output.
Key Features
- a threshold of 2.3 V (typical), providing a wider noise margin than would be possible with a receiver having the usual TTL threshold
- A strobe turns off all drivers (high impedance) but does not affect receiver operation
- The SN55138 is characterized for operation over the full military temperature range of – 55°C to 125°C
- The SN75138 is characterized for operation from 0°C to 70°C
- Please be aware that
