GENERAL DESCRIPTION
The ADATE205 is a complete, single-chip solution that
performs the pin electronics functions of driver, comparator,
and active load (DCL) for ATE applications. The active load can
be powered down if not used.
The driver is a proprietary design that features three active
modes: data high mode, data low mode, and term mode, as well
as an inhibit state.
The driver has low leakage (<10 nA) in High-Z mode. The
output voltage range is −1.5 V to +6.5 V to accommodate a wide
variety of test devices.
The ADATE205 supports four programmable Tr/Tf times for
applications where slower edge rates are required. The edge rate
selection is done via two static digital CMOS select bits. The
input data to the driver can be inverted using a single CMOS
logic bit. This feature can be used for system calibration or
applications where complement input data is needed.
