DS1776 - PI-Bus Transceiver

Datasheet Summary

Description

The DS1776 is an octal PI-bus Transceiver.

The A to B path is latched.

B outputs are open collector with series Schottky diode, ensuring minimum B output loading.

Features

  • a controlled linear ramp to minimize crosstalk and ringing on the bus. A separate high level control voltage (VX) is provided to prevent the A side output high level from exceeding future high density processor supply voltage levels. For 5V systems, VX is tied to VCC. Features n n n n n n n Mil-Std-883C qualified Similar to BTL Low power ICCL = 41 mA max B output controlled ramp rate B input noise immunity, typically 4 ns Available in 28-pin DIP, Flatpak and CLCC Pin and function compatible wit.

DS1776 PI-Bus Transceiver January 1996 DS1776 PI-Bus Transceiver General Description The DS1776 is an octal PI-bus Transceiver. The A to B path is latched. B outputs are open collector with series Schottky diode, ensuring minimum B output loading. B outputs also have ramped rise and fall times (2.5 ns typical), ensuring minimum PI-bus ringing. B inputs have glitch rejection circuitry, 4 ns typical. Designed using National’s Bi-CMOS process for both low operating and disabled power. AC performance is optimized for the PI-Bus inter-operability requirements. The DS1776 is an octal latched transceiver and is intended to provide the electrical interface to a high performance wired-or bus.
