4 / 16 page LM239A-EP SCLS496C – MAY 2003 – REVISED JULY 2010 www.ti.com ELECTRICAL CHARACTERISTICS at specified free-air temperature, VCC = 5 V (unless otherwise noted) PARAMETER TEST CONDITIONS(1) TA (2) MIN TYP MAX UNIT VCC = 5 V to 30 V, 25°C 1 2.5 VIO Input offset voltage VIC = VICR min, mV Full range 5.5 VO = 1.4 V 25°C 5 50 IIO Input offset current VO = 1.4 V nA Full range 150 25°C –25 –250 IIB Input bias current VO = 1.4 V nA Full range –400 0 to 25°C VCC – 1.5 Common-mode input-voltage VICR V range(3) 0 to Full range VCC – 2 Large-signal differential-voltage VCC = 15 V, VO = 1.4 V to 11.4 V, AVD 25°C 50 200 V/mV amplification RL ≥ 15 kΩ to VCC VOH = 5 V 25°C 0.1 50 nA IOH High-level output current VID = 1 V VOH = 30 V Full range 1 mA 25°C 150 400 VOL Low-level output voltage VID = –1 V, IOL = 4 mA mV Full range 700 IOL Low-level output current VID = –1 V, VOL = 1.5 V 25°C 6 16 mA Supply current ICC VO = 2.5 V, No load 25°C 0.8 2 mA (four comparators) (1) All characteristics are measured with zero common-mode input voltage, unless otherwise specified. (2) Full range (MIN to MAX) for LM139 and LM139A is –55°C to 125°C. All characteristics are measured with zero common-mode input voltage, unless otherwise specified. (3) The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage range is VCC+ – 1.5 V; however, one input can exceed VCC, and the comparator will provide a proper output state as long as the other input remains in the common-mode range. Either or both inputs can go to 30 V without damage. SWITCHING CHARACTERISTICS VCC = 5 V, TA = 25°C PARAMETER TEST CONDITIONS TYP UNIT 100-mV input step with 5-mV overdrive 1.3 RL connected to 5 V through 5.1 kΩ, Response time ms CL = 15 pF (1) (2) TTL-level input step 0.3 (1) CL includes probe and jig capacitance. (2) The response time specified is the interval between the input step function and the instant when the output crosses 1.4 V. 4 Submit Documentation Feedback Copyright © 2003–2010, Texas Instruments Incorporated Product Folder Link(s): LM239A-EP |
