BUFFER / DRIVER

Highland Technology logo
T340 features
  • General-purpose logic buffer and driver

  • Excellent as level translator, fet driver, laser driver, or clock buffer

  • Accepts single-ended or differential inputs with adjustable logic threshold.

  • Single-ended output is adjustable for Vlow and Vhigh levels, up to 2.6 volts swing into 50 ohms

  • Usable from DC to 1 GHz

  • External universal power supply or 12-volt DC power.

  • Rise/fall times below 200 ps, 1 volt into 50 ohms

  • OEM packaged or board-only custom available.
The T860 is a compact standalone logic buffer. It incorporates a differential-input comparator and an output driver stage which has adjustable low and high levels and 50 ohm output impedance. Vlow is adjustable from -4 to +4 volts (-2 to +2 into 50 ohms) and Vhigh can be set from -3.5 to +5.2 (-1.75 to 2.6 into 50 ohms.)

The T860 can source up to 100 mA while maintaining an excellent 50 ohm source termination, making it suitable for driving fets, lasers, or other unmatched loads.
Waveform shown: 300 MHz square wave output, 0 to +2 volts into 50 ohms.
