NTE1745中文资料NTE数据手册PDF规格书

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:

• High–Speed Operation (fmax = 130MHz)

• Operation at Low Input Amplitudes (180mVp–p Minimum Input Amplitude)

• 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.
