GENERAL DESCRIPTION
The HT506/507 monolithic multiplexers consist of sixteen
analog switches, 4-bit decode for channel selection, refer-
ence for logic switching thresholds, and enable pin for device
deactivation where applications require. These multiplexers
are fabricated with Honeywell’s dielectrically isolated latch-up
free high temperature (HTMOS™) linear process.
Performance is specified over the full -55 to +225°C
temperature range. Typically, parts will operate up to
+300°C for a year, with derated performance. All parts are
burned in at 250°C to eliminate infant mortality.
The input buffers are designed to operate from either TTL
or CMOS levels while providing a break-before-make ac-
tion. The HT506 switches one of sixteen inputs to a
common output, while the HT507 switches one of eight
differential inputs to a differential output. These parts are
available in standard pinout 28-pin DIPs.
