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.
