DS3884A

BTL Handshake Transceiver

n Glitch free power-up/down protection

General Description

n Typically less than 5 pF bus-port capacitance

n Low Bus-port voltage swing (typically 1V) at 80 mA

n TTL compatible driver and control inputs

n Separate TTL I/O

n Open collector bus-port outputs allow Wired-OR

connection

The DS3884A is one in a series of transceivers designed

specifically for the implementation of high performance Fu-

turebus+ and proprietary bus interfaces. The DS3884A is a

BTL 6-bit Handshake Transceiver designed to conform to

IEEE 1194.1 (Backplane Transceiver Logic—BTL) as speci-

fied in the IEEE 896.2 Futurebus+ specification.

n Controlled rise and fall time to reduce noise coupling to

adjacent lines

Features

n Built in Bandgap reference with separate QV

and

n Fast propagation delay (3 ns typ)

n 6-bit BTL transceiver

QGND pins for precise receiver thresholds

n Exceeds 2 kV ESD testing (Human Body Model)

n Individual Bus-port ground pins

n Selective receiver glitch filtering (FR1–FR3)

n Meets 1194.1 Standard on Backplane Transceiver Logic

(BTL)

n Product offered in PQFP package styles

n Supports live insertion
