NTE1639
Integrated Circuit
CMOS Clock Generator/Driver for BBDs
Description:
The NTE1639 is a CMOS LSI Clock Generator ina 8–Lead DIP type package capable of generating
two phase clock signals of low output impedance for use as a BBD driver. The built–in VGG power
supply circuit provides the proper voltages needed for driving BBDs such as the NTE1641.
Features:
D BBD Direct Driving Capability of up to two BBD’s
D Self and Separate Oscillations.
D Two Phase Clock Output (Duty: 1/2)
D Built–in VGG Voltage Generator for Driving the NTE1641 BBD.
D Single Power Supply: –8V to –16V.
Applications:
D BBD Clock Generator/Driver.
