Description
The SN55138 and SN75138 quadruple bus transceivers are designed for two-way data communication over single-ended transmission lines.
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. These circuits are designed for operation from a single 5-V supply and include a provision to minimize loading of the data bus when the power-supply voltage is zero. The SN55138 is characterized for operation over the full military temperature range of.
- 55°C to 125°C.
