Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime. Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3 V beyond the supply rails must be current-limited to 10 mA or less. Output terminals are diode-clamped to the power-supply rails.

The fast response time of these comparators make them well suited for applications that require narrow pulse width detection or high toggle frequencies. The TLV3601 is available in a 5-pin SC70 and SOT23 package, while the TLV3603(E) is packaged in a 6-pin SC70. The TLV3602 is a dual channel version of the TLV3601 and is packaged in an 8-pin VSSOP and WSON package. 7.2 Functional Block Diagram TLV3601 TLV3603 VCC VCC + + LE/HYST VEE VEE 7.3 Feature Description The TLV3601,TLV3603(E), and TLV3602 are single and dual channel, high speed comparators with a typical propagation delay of 2.5 ns and push-pull outputs. The minimum pulse width detection capability is 1.25 ns and the typical toggle rate is 325 MHz. These comparators are well-suited for distance measurement applications that utilize a time-of-flight arechitecture as well as systems that suffer from capacitive loading and require data and clock recovery. In addition to their high speed, the TLV360x family offers rail-to-rail input stages capable of operating up to 200 mV beyond each power supply rail combined with a maximum 5 mV input offset. The TLV3603(E) also provides adjustable hysteresis via an external resistor for noise suppression or a latching mode to hold the output of the comparators. 7.4 Device Functional Modes The TLV3601 has a single functional mode and is active when the power supply voltage is greater than 2.4V. The TLV3603(E) has two modes of operation. The first is an active mode where the output reflects the condition at the inputs when an external resistor is connected to ground on the LE/HYS pin. The second is a latch mode where the output is held at its last active state when the LE/HYS pin is pulled low. The TLV3603(E) returns to active mode after a short delay when the pin is pulled high. 7.4.1 Inputs The TLV360x family features input stages capable of operating 200 mV below negative power supply (ground) and 200 mV beyond the positive supply voltage, allowing for zero cross detection and maximizing input dynamic range given a certain power supply. The input stages are protected from conditions where the voltage on either pin exceeds this level by internal ESD protection diodes to VCC and VEE. To avoid damaging the inputs when exceeding the recommended input voltage range, an external resistor should be used to limit the current. 7.4.2 Push-Pull (Single-Ended) Output The TLV360x outputs have excellent drive capability and are designed to connect directly to CMOS logic input devices. Likewise, the comparator output stages can drive capacitive loads. Transient performance parameters in the Electrical Characteristics Tables and Typical Characteristics section are for a load of 5pF, corresponding to a standard CMOS load. Device performance for larger capacitive loads can be found in the typical performance curves titled Propagation Delay vs Capacitive Load. For optimal speed and performance, output load capacitance should be reduced as much as possible.

When the power supply (VCC) is ramping up or ramping down, the POR circuit will be active when VCC is below VPOR. When active, the POR circuit holds the output low at VEE. When VCC is greater than or equal to VPOR as stated in 节 6.5 , the comparator output reflects the state of the input pins. 图 7-1 shows how the TLV360x outputs respond for VCC rising. The input is configured with a logic high input to highlight the transition from the POR circuit control (logic low output) to a standard comparator operation where the output reflects the input condition. Note how the output goes high when VCC reaches 2.1V. 图 7-1.

TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. 8.1 Application Information 8.1.1 Adjustable Hysteresis As a result of a comparator’s high open loop gain, there is a small band of input differential voltage where the output can toggle back and forth between “logic high” and “logic low” states. This can cause design challenges for inputs with slow rise and fall times or systems with excessive noise. These challenges can be overcome by adding hysteresis to the comparator. Since the TLV3601 and TLV3602 only has a minimal amount of internal hysteresis, external hysteresis can be applied in the form of a positive feedback loop that adjusts the trip point of the comparator depending on its current output state. See the Implementing Hysteresis section for more details. The TLV3603(E) on the other hand has a LE/HYS pin that can be used to increase or eliminate the internal hysteresis of the comparator. In order to increase the internal hysteresis of the TLV3603(E), connect a single resistor as shown in the adjusting hysteresis figure between the LE/HYS pin and VEE. A curve of hysteresis versus resistance is provided below to provide guidance in setting the desired amount of hysteresis. Likewise, for applications where no hysteresis is desired, the LE/HYS pin can be connected to VCC. VCC TLV3603 IN+ + OUT IN- LE/HYS VEE 图 8-1.

However, excessive capacitive loading under high switching frequencies may increase supply current, propagation delay, or induce decreased slew rate. 8.1.3 Latch Functionality The latch pin for the TLV3603(E) holds the output state of the device when the voltage at the LE/HYS pin is a logic low. This is particularly useful when the output state is intended to remain unchanged. An important consideration of the latch functionality is the latch hold and setup times. Latch hold time is the minimum time required (after the latch pin is asserted) for properly latching the comparator output. Likewise, latch setup time is defined as the time that the input must be stable before the latch pin is asserted low. The figure below illustrates when the input can transition for a valid latch. Note that the typical setup time in the EC table is negative; this is due to the internal trace delays of the LE/HYS pin relative to the input pin trace delays. A small delay (tPL) in the output response is shown below when the TLV3603(E) exits a latched output stage. tSETUP tHOLD LE/HYS IN Valid Input Transition Region Invalid Input Transition Region Valid Input Transition Region 图 8-3.

This usually occurs when the input signal is moving very slowly across the switching threshold of the comparator. This problem can be prevented by using the internal hysteresis feature of the comparator or by the addition of external hysteresis. The TLV3603(E) has a LE/HYS pin that allows for variable internal hysteresis depending on the resistor value connected between the pin and VEE, where increasing the resistance decreases the hysteresis to a minimum level.

Figure 8-2 shows that for a 30-mV hysteresis, a 150 kΩ resistor must be placed from the LE/HYS pin to VEE.
