NTE744  
Integrated Circuit  
RF/IF Amp  
Description:  
The NTE744 is a monolithic silicon integrated circuit that provides an rf amplifier, if amplifier, mixer,  
oscillator, AGC detector, and voltage regulator on a single chip. It is intended for use in super–hetero-  
dyne AM radio receiver applications particularly in automobiles. The NTE744 is supplied in a 14–lead  
dual–in–line plastic package and operates over the temperature range of –55° to 125°C.  
Features:  
D Low–noise, low–Rb, rf stage in cascode connection–eliminates Miller–Effect regeneration and  
allows controlled power rise by the choice of external components.  
D Mixer–oscillator stage with internal feedback–eliminates need for tapped or multi–winding os-  
cillator coils  
D Cascode if amplifier with controlled output impedance and negligible Miller Effect–eliminates  
regeneration and selectivity skewing  
D Frequency–counter AGC circuit–allows control of AGC response by selection of the coupling  
capacitor.  
D Integral regulation with built–in surge protection  
D Separately accessible amplifiers
