These devices have been developed specifically for low-voltage, single-supply applications. Their enhanced performance makes them excellent replacements for the LM393 in the improved 3-V and 5-V system designs of today. The TLV1391, with its typical supply current of only 80 µA, is ideal for low-power systems. Response time also has been improved to 0.7 µs. The TLV1391C is characterized for operation from 0°C to 70°C and the TLV1391I is characterized for operation from –40°C to 85°C.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, except differential voltages, are with respect to the network GND. 2. Differential voltages are at the noninverting input with respect to the inverting input. 3. Short circuits from the outputs to VCC can cause excessive heating and eventual destruction of the chip. 4. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability. 5. The package thermal impedance is calculated in accordance with JESD 51. recommended operating conditions MIN Supply voltage, VCC TLV1391C Operating O erating free-air tem temperature erature, TA TLV1391I POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 MAX 2 7 0 70 – 40 85 UNIT V °C 3 TLV1391 SINGLE DIFFERENTIAL COMPARATORS SLCS128B – APRIL 1996 – REVISED JUNE 1999 electrical characteristics, VCC = 3 V PARAMETER VIO VICR VOL Input offset voltage VO = 1 1.4 4V V, VIC = VICR(min) TLV1391C TA† TEST CONDITIONS MIN 25°C 1.5 Full range VID = –1 V, IOL = 500 µA 0 to VCC – 1.5 Input offset current 4V VO = 1 1.4 IIB Input bias current VO = 1 1.4 4V IOH High level output current High-level VID = 1 V, VID = 1 V, VOH = 3 V VOH = 5 V IOL Low-level output current VID = –1 V, VOL = 1.5 V ICC(H) High level supply current High-level VO = VOH ICC(L) Low level supply current Low-level VO = VOL 5 Full range 0 to VCC – 2 Full range 120 V 300 5 Full range 50 150 25°C – 40 Full range –250 – 400 25°C 0.1 Full range 25°C UNIT mV 0 to VCC – 1.2 25°C IIO MAX 9 25°C Common mode input voltage range Common-mode Low-level output voltage TYP 100 mV nA nA nA µA 500 25°C 80 Full range 125 150 25°C 80 Full range 125 150 µA µA † Full range is 0°C to 70°C. switching characteristics, VCC = 3 V, CL = 15 pF‡, TA = 25°C PARAMETER Response time 100-mV input step with 5-mV overdrive, ‡ CL includes the probe and jig capacitance. 4 TLV1391C TEST CONDITIONS POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 MIN RL = 5.1 kΩ TYP 0.7 MAX UNIT µs TLV1391 SINGLE DIFFERENTIAL COMPARATORS SLCS128B – APRIL 1996 – REVISED JUNE 1999 electrical characteristics, VCC = 5 V PARAMETER VIO VICR VOL Input offset voltage VO = 1 1.4 4V V, VIC = VICR(min) VID = –1 V, IOL = 500 µA 25°C Input offset current 4V VO = 1 1.4 IIB Input bias current VO = 1 1.4 4V IOH High level output current High-level VID = 1 V, VID = 1 V, VOH = 3 V VOH = 5 V IOL Low-level output current VID = –1 V, VOL = 1.5 V VO = VOH ICC(L) VO = VOL Low level supply current Low-level TYP MAX 1.5 5 9 25°C 0 to VCC – 1.5 Full range 0 to VCC – 2 0 to VCC – 1.2 Full range 25°C IIO ICC(H) High-level High level supply current MIN Full range Common mode input voltage range Common-mode Low-level output voltage TLV1391C TA† TEST CONDITIONS 300 5 50 150 25°C – 40 Full range 0.1 Full range 25°C –250 – 400 25°C mV V 120 Full range UNIT 100 mV nA nA nA µA 600 25°C 100 Full range 150 175 25°C 100 Full range 150 175 µA µA † Full range is 0°C to 70°C. switching characteristics, VCC = 5 V, CL = 15 pF‡, TA = 25°C PARAMETER Response time TLV1391C TEST CONDITIONS MIN TYP 100-mV input step with 5-mV overdrive, RL = 5.1 kΩ 0.65 TTL-level input step, RL = 5.1 kΩ 0.18 MAX UNIT µs ‡ CL includes the probe and jig capacitance.
