CO393 Dual comparators The CO393 is dual comparators with open-collector output which allows wired OR connections. The operating power supply voltage ranges from 2 to 36V for a single power supply and ± 1 to ± 18V for a dual power supply. The packages are as follows: DIP 8-pin, SOP 8-pin. •1)Features Wide operating voltage range. 4) Wide common-mode input voltage. (0 to VCC – 1.5V) 5) Open collector output. 6) Compatible with 393 comparators from other manufacturers. (Single power supply: 2 to 36V, dual power supply: ± 1 to ± 18V) 2) Low current dissipation. (0.4mA typ. at VCC = 5V) 3) Low input offset current. (25nA typ. at VCC = 5V) and low input offset voltage. (typically ±1.0mV at VCC = 5V) •Block diagram CO393 OUT1 1 – IN1 2 – + IN1 3 VEE 4 1ch 8 VCC 7 OUT2 6 – IN2 5 + IN2 + + 2ch – •Internal circuit configuration VCC + IN OUT – IN GND * All specs and applications shown above subject to change without prior notice. 1F-5 NO.66 SEC.2 NAN-KAN RD ., LUCHU , TAOYUAN, TAIWAN Email: [email protected] Tel:886-3-3214525 Http: www.ceramate.com.tw Page 1 of 4 Rev 1.0 Apr. 28, 2003 Fax:886-3-3521052 CO393 Dual comparators •Absolute maximum rating (Ta = 25°C) Parameter Limits Symbol CO393 (DIP-8) CO393 (SOP-8) Unit Power supply voltage Vcc 36(±18) 36(±18) V Power dissipation Pd VID 550* ±VCC mW Differential input voltage 800* ±VCC VI -0.3~Vcc -0.3~Vcc Common-mode input voltage V Operating temperature Topr -40~+85 -40~+85 V ℃ Storage temperature Tstg -55~+125 -55~+125 ℃ * Refer to the Pd characteristics diagram. •Electrical characteristics (unless otherwise noted, Ta = 25°C, V CC Parameter = + 5V) Symbol Min.
