NTE1639

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.
