HT506

High Temperature Analog Multiplexers 16-Channel Single-Ended / 8-Channel Differential HT506 / HT507 The High Temperature HT506/HT507 monolithic multiplexers consist of sixteen analog switches, 4-bit decode for channel selection, reference 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 +225ºC temperature range. Typically, parts will operate up to +300ºC for a year, with derated performance. All parts are burned in at 250ºC. The input buffers are designed to operate from either TTL or CMOS levels while providing a break-before-make action. The HT506 switches one of the sixteen single-ended inputs to a common output, while the HT507 switches one of the eight differential inputs to a differential output. These parts are available in standard pinout 28-pin DIP Ceramic Packages.
