About this item

  • SINGLE-CHANNEL: TLV3501 is a single-channel high-speed push-pull output comparator, delay is 4.5ns, supply voltage: + 2.7V to + 5.5V
  • FRONT SHAPING MODULE: This module can be for a wide range of voltage signal shaping period, as the frequency, phase difference time domain measurements and other front-end conditioning module
  • CMOS AND TTL: Rail-to-rail output can directly drive a CMOS or TTL logic
  • EASY TO OPERATE: Without threshold setting, the sine wave, square wave and triangular wave can be transformed into square wave, which can be used easily without debugging
  • GREAT EXTENSIBILITY: At the same time, it has great extensibility, just change a small amount of the original


TLV3501 is a single-channel high-speed push-pull output comparator, delay is 4.5ns, supply voltage: + 2.7V to + 5.5V, has exceeded swing input common-mode range makes it ideally suited for low voltage applications. Rail-to-rail output can directly drive a CMOS or TTL logic. This module can be for a wide range of voltage signal shaping period, as the frequency, phase difference time domain measurements and other front-end conditioning module, can be used as the 2015 National Undergraduate Electronic Design Contest F digital frequency meter title front-end module.

I just got the time to test the Assembly today and it would not output a pulse when driven by a suitable signal. After fussing with it for a while I started measuring all the pins individually and when I put the probe on pin 8 the device came to life. Inspection under a microscope had already revealed a suspect solder joint and this one pin, which when left 'floating' will disable the device. That is why the SHDN is called 'shutdown' . Anyway, after re-soldering the pin, the device performed as expected and its characteristics seem at or close enough to satisfy me that the test board was worth the $20. The jumper was left on for my purposes.
