19-1129; Rev 4; 3/99 Single/Dual/Quad, Ultra-High-Speed, +3V/+5V, Beyond-the-Rails Comparators ____________________________Features The MAX961–MAX964/MAX997/MAX999 are low-power, ultra-high-speed comparators with internal hysteresis. These devices are optimized for single +3V or +5V operation. The input common-mode range extends 100mV Beyond-the-Rails™, and the outputs can sink or source 4mA to within 0.52V of GND and V CC . Propagation delay is 4.5ns (5mV overdrive), while supply current is 5mA per comparator. ♦ Ultra-Fast, 4.5ns Propagation Delay The MAX961/MAX963/MAX964 and MAX997 have a shutdown mode in which they consume only 270µA supply current per comparator. The MAX961/MAX963 provide complementary outputs and a latch-enable feature. Latch enable allows the user to hold a valid comparator output. The MAX999 is available in a tiny SOT23-5 package. The single MAX961/MAX997 and dual MAX962 are available in space-saving 8-pin µMAX packages. ________________________Applications ♦ Ideal for +3V and +5V Single-Supply Applications ♦ Beyond-the-Rails Input Voltage Range ♦ Low, 5mA Supply Current (MAX997/MAX999) ♦ 3.5mV Internal Hysteresis for Clean Switching ♦ Output Latch (MAX961/MAX963) ♦ TTL/CMOS-Compatible Outputs ♦ 270µA Shutdown Current per Comparator (MAX961/MAX963/MAX964/MAX997) ♦ Available in Space-Saving Packages: 5-Pin SOT23 (MAX999) 8-Pin µMAX (MAX961/MAX962/MAX997) 16-Pin QSOP (MAX964) _______________Ordering Information Single 3V/5V Systems Portable/Battery-Powered Systems PART Threshold Detectors/Discriminators GPS Receivers Line Receivers Zero-Crossing Detectors High-Speed Sampling Circuits ______________________Selector Guide TEMP RANGE PINPACKAGE SOT TOP MARK MAX961ESA -40°C to +85°C 8 SO — MAX961EUA MAX962ESA MAX962EUA MAX963ESD MAX964ESE MAX964EEE MAX997ESA MAX997EUA -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C — — — — — — — — 8 µMAX 8 SO 8 µMAX 14 SO 16 Narrow SO 16 QSOP 8 SO 8 µMAX Yes Yes 8 SO/µMAX MAX962 2 No No No 8 SO/µMAX MAX963 2 Yes Yes Yes 14 SO MAX964 4 No Yes No 16 SO/QSOP MAX997 1 No Yes No 8 SO/µMAX MAX999 1 No No No 5 SOT23 PACKAGE Yes LATCH ENABLE SHUTDOWN 1 NO.

Note 2: Inferred by CMRR. Either input can be driven to the absolute maximum limit without false output inversion, provided that the other input is within the input voltage range. Note 3: The input-referred trip points are the extremities of the differential input voltage required to make the comparator output change state. The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis zone. (See Figure 1.) Note 4: Input offset voltage is defined as the mean of the trip points. Note 5: CMRR = (VOSL - VOSH) / 5.2V, where VOSL is the offset at VCM = -0.1V and VOSH is the offset at VCM = 5.1V. Note 6: PSRR = (VOS2.7 - VOS5.5) / 2.8V, where VOS2.7 is the offset voltage at VCC = 2.7V, and VOS5.5 is the offset voltage at VCC = 5.5V. Note 7: Propagation delay for these high-speed comparators is guaranteed by design characterization because it cannot be accurately measured using automatic test equipment. A statistically significant sample of devices is characterized with a 200mV step and 100mV overdrive over the full temperature range. Propagation delay can be guaranteed by this characterization, since DC tests ensure that all internal bias conditions are correct. For low overdrive conditions, VTRIP is added to the overdrive. Note 8: Guaranteed by design. _______________________________________________________________________________________ 3 __________________________________________Typical Operating Characteristics (VCC = +3.0V, CLOAD = 5pF, 5mV of overdrive, TA = +25°C, unless otherwise noted.)

Their outputs are guaranteed to pull within 0.52V of either rail without external pull-up or pull-down circuitry. Beyondthe-Rails™ input voltage range and low-voltage, singlesupply operation make these devices ideal for portable equipment. These comparators all interface directly to CMOS logic. Timing Most high-speed comparators oscillate in the linear region because of noise or undesirable parasitic feedback. This can occur when the voltage on one input is close to or equal to the voltage on the other input. These devices have a small amount of internal hysteresis to counter parasitic effects and noise. The added hysteresis of the MAX961–MAX964/MAX997/ MAX999 creates two trip points: one for the rising input voltage and one for the falling input voltage (Figure 1). The difference between the trip points is the hysteresis. When the comparator’s input voltages are equal, the hysteresis effectively causes one comparator input voltage to move quickly past the other, thus taking the input out of the region where oscillation occurs. Standard comparators require hysteresis to be added with external resistors. The fixed internal hysteresis eliminates these resistors. The MAX961/MAX963 include internal latches that allow storage of comparison results. LE has a high input impedance. If LE is low, the latch is transparent (i.e., the comparator operates as though the latch is not present). The comparator’s output state is stored when LE is pulled high. All timing constraints must be met when using the latch function (Figure 2). Input Stage Circuitry The MAX961–MAX964/MAX997/MAX999 include internal protection circuitry that prevents damage to the precision input stage from large differential input voltages. This protection circuitry consists of two groups of three front-to-back diodes between IN+ and IN-, as well as two 200Ω resistors (Figure 3). The diodes limit the differential voltage applied to the comparator’s internal circuitry to no more than 3VF, where VF is the diode’s forward-voltage drop (about 0.7V at +25°C).

(IN+ - IN-) - 3VF Input current = ———————— 2 x 200 Input currents with large differential input voltages should not be confused with input bias currents (IB). As long as the differential input voltage is less than 3VF, this input current is less than 2IB. The input circuitry allows the MAX961–MAX964/ MAX997/MAX999’s input common-mode range to extend 100mV beyond both power-supply rails. The output remains in the correct logic state if one or both inputs are within the common-mode range. Taking either input outside the common-mode range causes the input to saturate and the propagation delay to increase. Figure 3.

MAX961 PC Board Layout Figure 4. Output Stage Circuitry Output Stage Circuitry The MAX961–MAX964/MAX997/MAX999 contain a current-driven output stage, as shown in Figure 4. During an output transition, ISOURCE or ISINK is pushed or pulled to the output pin. The output source or sink current is high during the transition, creating a rapid slew rate. Once the output voltage reaches VOH or VOL, the source or sink current decreases to a small value, capable of maintaining the VOH or VOL in static condition. This decrease in current conserves power after an output transition has occurred. One consequence of a current-driven output stage is a linear dependence between the slew rate and the load capacitance. A heavy capacitive load slows down the voltage output transition. Shutdown Mode When SHDN is high, the MAX961/MAX963/MAX964/ MAX997 shut down. When shut down, the supply current drops to 270µA per comparator, and the outputs become high impedance. SHDN has a high input impedance. Connect SHDN to GND for normal operation. Exit shutdown with LE low; otherwise, the output is indeterminate. __________Applications Information Circuit Layout and Bypassing The MAX961–MAX964/MAX997/MAX999’s high bandwidth requires a high-speed layout. Follow these layout guidelines: 1) Use a printed circuit board with a good, unbroken, low-inductance ground plane. 2) Place a decoupling capacitor (a 0.1µF ceramic surface-mount capacitor is a good choice) as close to VCC as possible. 3) On the inputs and outputs, keep lead lengths short to avoid unwanted parasitic feedback around the comparators. Keep inputs away from outputs. Keep impedance between the inputs low. 4) Solder the device directly to the printed circuit board rather than using a socket. 5) Refer to Figure 5 for a recommended circuit layout. 6) For slow-moving input signals, take care to prevent parasitic feedback. A small capacitor (1000pF or less) placed between the inputs can help eliminate oscillations in the transition region. This capacitor causes negligible degradation to t PD when the source impedance is low. _______________________________________________________________________________________ 9 MAX961–MAX964/MAX997/MAX999 VCC MAX961–MAX964/MAX997/MAX999 Single/Dual/Quad, Ultra-High-Speed, +3V/+5V, Beyond-the-Rails Comparators ___________________________________________________________Pin Configurations TOP VIEW 8 VCC INA+ 1 7 Q INA- 2 SHDN 3 6 Q LE 4 5 GND IN+ 1 IN- 2 MAX961 8 VCC 7 QA INB+ 3 6 QB INB- 4 5 GND MAX962 SO/µMAX SO/µMAX INA- 1 14 QA INA- 1 16 N.C.
