Bare Die Data Sheet: CD4046B

Phase locked loop (PLL) with x2 phase comparators, voltage-controlled oscillator (VCO), source follower & zener. Comparators have a common signal input amplifier & common comparator input. The zener diode regulates power supply if required.
Direct replacement for legacy Fairchild CD4046B, National CD4046B, Harris or RCA CD4046B, Motorola MC14046B & Texas Instruments CD4046BH. Operating over the full military temperature range this bare die is well suited for hi-rel applications.
Features:
** END OF LIFE ** NOT RECOMMENDED FOR NEW DESIGN
  • Choice of two Phase Comparators:
    • Exclusive Or Gate, duty cycle limited
    • Rising edge switching, duty cycle unlimited.
  • Buffered outputs compatible with MHTL and Low power TTL
  • VCO inhibit control for ON-OFF keying and ultra-low standby power consumption
  • Source-follower output of VCO control input
  • Integrated zener diode to assist supply regulation
  • High Input Voltage up to 20V
  • Specified at 5V, 10V & 15V
  • Military Temperature Range for High Reliability
  • Smaller die size versus peers
