. . . with single conversion circuitry including oscillator, mixer, IF amplifiers,  
limiting IF circuitry, and quadrature discriminator. 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

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.
