(IO = 4mA) FFERENTIAL INPUT VOLTAGE RANGE EQUAL TO THE SUPPLY VOLTAGE DTL, ECL, MOS, CMOS COMPATIBLE OUTPUTS L SOT23-5L (Tiny Package) DESCRIPTION These devices consist of a low power voltage comparator designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. This comparator also has a unique characteristic in that the input common-mode voltage range includes ground eventhough operatedfrom a single power supply voltage.

At output sw it ch point, VO 1.4V, RS = 0 with VCC + f rom 5V to 30V and over the full input common-mode range (0V to VCC+ 1.5V). 3. T he direction of the input cur rent is out of the IC due t o the PNP input stage. This cur rent is essenti ally constant, i ndependent of the state of the output, so no loading charge exists on the reference or input l ines. 4. T he input common-mode voltage of either i nput signal volt age should not be allow ed to go negati ve by more than 0.3V. T he upper end of the common-mode voltage range i s VCC + -1.5V, but either or bot h inputs can go to +30V without damage. 5. T he response time specifi ed is for a 100mV input step wi th 5mV overdr ive. F or lar ger overdrive signals 300ns can be obtained. 6. Positive excursions of input volt age may exceed the power suppl y level. As long as the other voltage remains wit hin the common-mode range the comparat or wi ll provi de a proper output state. The l ow input vol tage st ate must not be l ess than -0.3V (or 0.3V below the negative power supply, if used). 3/5 TS391 SUPPLY CURRENT versus SUPPLY VOLTAGE 0.5 SUPPLY CURRENT (mA) 0.4 0.3 Ta m b = +70 C INPUT CURRENT versus SUPPLY VOLTAGE 80 Vi = 0V INPUT CURRENT (nA) 60 40 20 Tamb = +125C Tamb = +70C 40 0 10 20 30 SUPPLY VOLTAGE (V) 40 R i = 10 Tamb = 0C Tamb = +25C 9 Ta mb = -55 C Ta mb = 0 C T = +25 C Tamb = -55C 0.2 Tamb = +125 C 0.1 R= 0 10 20 30 S UP P LY VOLTAGE (V) OUTPUT SATURATION VOLTAGE versus OUTPUT CURRENT 10 10 10 10 10 1 RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES - NEGATIVE TRANSITION OUTPUT VOLTAGE(V) SATURATION VOLTAGE(V) Out of saturation 0 Tamb = +125C -1 -2 Tamb = +25C -3 -2 -1 0 1 2 INPUT VOLTAGE(mV) Tamb = -55C 6 5 4 3 2 1 0 0 -50 -100 Input overdrive : 5mV 20mV eI 5V 5.1k eo 100mV Tamb = +25C 0 0.5 1 1.5 TIME (s) 2 10 10 10 10 10 OUTPUT SINK CURRENT (mA) RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES - POSITIVE TRANSITION OUTPUT VOLTAGE (V) 6 Input overdrive : 100mV 5 4 5mV 3 2 20mV 1 0 100 Tamb = +25C 50 0 0 0.5 1 1.5 TIME (s) 5V 5. 1 k e I INPUT VOLTAGE(mV) eo 2 4/5 TS391 PACKAGE MECHANICAL DATA 5 PINS -TINY PACKAGE (SOT23) A E A2 D b A1 E1 C L Dim.
