DS3667 TRI-STATE Bidirectional Transceiver
General Description
The DS3667 is a high-speed Schottky 8-channel bidirection-
al transceiver designed for digital information and communi-
cation systems Pin selectable totem-pole open collector
outputs are provided at all driver outputs This feature to-
gether with the Dumb Mode which puts both driver and re-
ceiver outputs in TRI-STATE at the same time means high-
er flexibility of system design PNP inputs are used at all
driver inputs for minimum loading and hysteresis is provid-
ed at all receiver inputs for added noise margin A power
up down protection circuit is included at all outputs to pro-
vide glitch-free operation during V_CC power up or down
