Request InfoDrives Four Signals into 50-Ohm LoadsPulse Research LabTORRANCE, Calif., June 23 -- Pulse Research Lab (PRL) is offering a PRL-444 four-channel, high-input-impedance, 50-ohm TTL (transistor-transistor logic) line driver. This compact, self-contained buffer pod drives four TTL/CMOS signals into 50 ohm loads. With a 10-k ohm input impedance, the new, ready-to use PRL-444 can receive signals from devices with low drive current, such as sensors, PC-based digital I/O cards, satellite receivers, optical transceivers, camera triggers, recorders and laboratory equipment with TTL/CMOS outputs. Each input has a 10-k ohm pulled up to 2.5 V so it can also...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2022 IssuePosition-Sensing DetectorThe high-sensitivity, 2-mm-diameter APX-PSD-XVInG-3.1 Position-Sensing Detector (PSD) from Advanced Photonix features spectral response from the visible to NIR and SWIR wavelengths.
