HI-8421, HI-8424

6-Channel / 8-Channel Discrete-to-Digital Interface

Sensing 28V / Open Signals

August 2010

DESCRIPTION

FEATURES

! 6 or 8 independent 28V / Open sensing channels

The HI-8421 is a six channel discrete-to-digital interface

device.The HI-8424 has eight channels. Mixed-signal

CMOS technology is used to provide superior low-power

performance. The device inputs are configured to sense

28V / Open discrete signals. The device outputs are CMOS

/ TTL compatible and may be disabled (tri-state) using the

CE and OE pins.

! 5.0V single supply operation

! Low power CMOS technology

! Industrial and ExtendedTemperatures

! HI-8421 is a drop in replacement for DEI1054

The HI-8421 is a drop-in replacement for the DEI1054.

For added functionality, the Holt HI-8422 offers eight

channels of Open / Ground sensing and eight channels of

28V / Ground sensing in a single device.
