As well as ultrasonic or infra-red transmission, cable, radio or telephone links may also be used. Pulse Position Modulation (PPM) is used with or without carrier and automatic error detection is incorporated. Initially designed with TV remote control in mind, the device is also suitable for use in radios, tuners, tape and record decks, lamps and lighting, toys and models, industrial control and monitoring. The SL490B is an easily extendable, 32-command PPM transmitter drawing negligible standby current. FEATURES s Ultrasonic or Infra-Red Transmission s Direct Drive or Ultrasonic Transducer s Direct Drive of Visible LED when using Infra-Red s Very Low Power Requirements s Pulse Position Modulation gives Excellent Immunity from Noise and Multipath Reflections s Single Pole Key Matrix s Switch Resistance up to 1k Ω Tolerated s Low External Component Count s On-Chip Anti-Bounce Circuitry (Supersedes version in April 1994 Consumer IC Handbook, HB3120 - 2.0) |
