The MC3374 is perfect for narrowband audio and data applications up to 75 MHz which require extremely low power consumption. Battery-powered applications down to VCC = 1.1 V are possible. The MC3374 also includes an onboard voltage regulator, low battery detection circuitry, a receiver enable allowing a power down Sleep–Mode, two undedicated buffer amplifiers to allow simultaneous audio and data reception, and a comparator for enhancing FSK (Frequency Shift Keyed) data reception to 1200 baud.
