MAX900–MAX903 High-Speed, Low-Power Voltage Comparators ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VCC = +5V, VEE = -5V, VDD = +5V, LE1–LE4 = logic high, TA = +25°C, unless otherwise noted.) Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specificatio ns is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The upper-end of the common-mode voltage range is typically VCC - 2V, but either or both inputs can go to a maximum of VCC + 0.2V without damage. Note 2: Tested for +4.75V < VCC < +5.25V, and -5.25V < VEE < -4.75V with VDD = +5V, although permissible analog power-supply range is +4.75V < VCC < +10.5V for single-supply operation with VEE grounded. Note 3: Specification does not apply to MAX901. Note 4: Guaranteed by design. Times are for 100mV step inputs (see Propagation Delay Characteristics in Figures 2 and 3). Note 5: Maximum difference in propagation delay between any of the four comparators in the MAX900–MAX903. Note 6: See Timing Diagram (Figure 2). Owing to the difficult and critical nature of switching measurements involving the latch, these parameters cannot be tested in a production environment. Typical specifications listed are taken from measurements using a high-speed test-jig. for +4.75V < VDD < +5.25V with the worst-case condition of all four comparator outputs at logic low.

MAX900–MAX903 High-Speed, Low-Power Voltage Comparators Definitions of Terms VOS Input Offset Voltage: Voltage applied between the two input terminals to obtain TTL-logic threshold (+1.4V) at the output. tpd+ (D) Latch Disable-to-Output High Delay: The propagation delay measured from the latch-signal crossing the TTL threshold in a low-to-high transition to the point of the output crossing TTL threshold in a low-to-high transition. V IN Input Voltage Pulse Amplitude: Usually set to 100mV for comparator specifications. t pd- (D) Latch Disable-to-Output Low Delay: The propagation delay measured from the latch-signal crossing the TTL threshold in a low-to-high transition to the point of the output crossing TTL threshold in a high-to-low transition.
