NTE1745 Datasheet | NTE Electronics

Description : The NTE1745 is a semiconductor integrated circuit in an 8- Lead SIP type package consisting of a built- in 1/20 and 1/100 high- speed frequency divider featuring an ECL circuit configuration. Features : D High- Speed Operation (fmax = 130MHz) D Operation at Low Input Amplitudes (180m Vp- p Minimum Input Amplitude) D TTL Level Output Applications: FM radio prescalers, digital equipment for consumer and industrial applications Function: This divider is based on an ECL circuit configuration. When a frequency up to a maximum of 130MHz is applied to the TI input pin, 1/20- divided output is produced when the division ratio selection input pin (M) is low- level or a 1/100- divided output is produced when the division ratio selection input pin (M) is high- level. The output (TO) is available in the TTL level open collector format.
