UNISONIC TECHNOLOGIES CO., LTD ULC3702 Advance CMOS IC DUAL MICROPOWER CMOS VOLTAGE COMPARATORS DESCRIPTION The UTC ULC3702 consists of two independent micropower voltage comparators designed to operate from a single supply and be compatible with modern HCMOS logic systems. The push-pull CMOS output stage drives capacitive loads directly without a power-consuming pullup resistor to achieve the stated response time. Eliminating the pullup resistor not only reduces power dissipation, but also saves board space and component cost. The output stage is also fully compatible with TTL requirements. FEATURES * Push-Pull CMOS Output Drives Capacitive Loads Without Pullup Resistor, IO=± 8mA * Very Low Power: 100µW (Typ.) at 5V * Fast Response Time tPLH=2.7µs (Typ.) With 5-mV Overdrive * Single-Supply Operation: 3V ~ 16V ORDERING INFORMATION Ordering Number Lead Free Halogen Free ULC3702L-D08-T ULC3702G-D08-T ULC3702G-S08-R Package Packing DIP-8 SOP-8 Tube Tape Reel MARKING DIP-8 www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd SOP-8 1 of 5 QW-R104-010.a ULC3702 Advance PIN CONFIGURATION PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 PIN NAME 1OUT 1IN1IN+ GND 2IN+ 2IN2OUT VDD CMOS IC DESCRIPTION Channel 1 output pin Inverting input for channel 1 Non-inverting input for channel 1 Ground Non-inverting input for channel 2 Inverting input for channel 2 Channel 2 output pin Supply voltage input pin BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R104-010.a ULC3702 Advance CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER Supply Voltage Range (Note 1) Differential Input Voltage (Note 2) Input Voltage Range Output Voltage Range Input Current Output Current (Each Output) Total Supply Current into VDD Total Current Out of GND SYMBOL VDD VID VI VO II IO RATINGS -0.3 ~ 18 ±18 -0.3 ~ VDD -0.3 ~ VDD ±5 ±20 40 40 1000 725 UNIT V V V V mA mA mA mA mW mW DIP-8 PD SOP-8 Lead Temperature 1,6 mm (1/16 Inch) from TL 260 °C Case for 10 Seconds Operating Free-Air Temperature Range TA -40~85 °C Storage Temperature Range TSTG -65~150 °C Notes: 1.
