description (continued)
The TRC1300 and TRC1315 include several on-chip functions that normally require additional circuitry in a
system design. These include an amplifier/comparator for detection and shaping of input signals as low as a
few millivolts (typically when an RF link is used) and a variable-frequency internal oscillator to clock the
transmitted or received security code.
The TRC1300 and TRC1315 MARCSTAR I E/D remote control encoder/decoders are characterized for
operation over the temperature range of – 40
°C to 85°C and are available in 14-pin SOIC small-outline IC
surface-mount (D) and 16-pin PDIP plastic dual in-line (N) packages.
