Layout Guidelines

The TLV3201 and TLV3202 are fast-switching, high-speed comparators and require high-speed layout considerations. For best results, maintain the following layout guidelines.

  • Use a printed-circuit board (PCB) with a good, unbroken low-inductance ground plane.
  • Place a decoupling capacitor (0.1µF ceramic, surface-mount capacitor) as close as possible to VCC.
  • On the inputs and the output, keep lead lengths as short as possible to avoid unwanted parasitic feedback around the comparator. Keep inputs away from the output.
  • Solder the device directly to the PCB rather than using a socket.
  • 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 some degradation to propagation delay when the impedance is low. The topside ground plane runs between the output and inputs.
  • The ground pin ground trace runs under the device up to the bypass capacitor, shielding the inputs from the outputs.
