75T203 Product details

Description

w The 75T202 and 75T203 are complete Dual-tone Multifrequency (DTMF) receivers detecting a selectable group of 12 or 16 standard digits.No front-end pre-filtering is needed.The only externally required components are an inexpensive 3.58 MHz television “colorburs” crystal (for frequency reference) and a bias resistor.Extremely high system density is made possible by using the clock output of a crystal-connected 75T202 or 75T203 receiver to drive the time bases of additional receivers.Both a

Features

Central office quality NO front-end band-splitting filters required Single, low-tolerance, 5-volt supply Detects either 12 or 16 standard DTMF digits Uses inexpensive 3.579545 MHz crystal for reference Excellent speech immunity Output in either 4-bit hexadecimal code or binary coded 2-of-8 18-pin DIP package for high system density Synchronous or handshake interface Three-state outputs E.
