SN75138N - QUADRUPLE BUS TRANSCEIVERS

Download the SN75138N datasheet PDF (SN75138 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for 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.
