SN55138 - QUADRUPLE BUS TRANSCEIVERS

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.

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.
