LTC1045CN#PBF

LTC1045 is a hex level translator manufactured using Linear Technology’s enhanced LTCMOSTM silicon gate process. It consists of six high speed comparators with output latches and three-state capability. Each comparator’s plus input is brought out separately. The minus inputs of comparators 1 to 4 are tied to VTRIP1 while 5 and 6 are tied to VTRIP2. The ISET pin has several functions. When taken to V+ the outputs are latched and power is completely shut off. Power/speed can be programmed by connecting ISET to V- through an external resistor. It is used in application like TTL/CMOS to ±5V analogue switch drive, TTL to CMOS (3V to 15V VCC, ECL to CMOS (3V to 15V VCC), ground isolation buffer, low power RS232 line receiver etc.

• Efficiently translate voltage levels
• Internal hysteresis for noise immunity
• Output latches included, three-state outputs
• Programmable power/speed, response time is 250ns maximum
• Power can be completely shut off
• ±50V on inputs with external 100K limit resistor
• V+ to V- supply current is 2.5mA typical at (DISABLE = V+, RSET = 10K)
• Input bias current is ±1nA typical at (V- ≤ VIN ≤ V+)
• Operating temperature is -40°C to 85°C
• Package style is 20-lead PDIP
