CD4543B - BCD-to-7-Segment Latch/Decoder/Driver

General Description

The CD4543BM is a monolithic CMOS BCD-to-7-segment latch/decoder/driver for use with liguid crystal and other types of displavs.

The circuit provides the func.

tions of a 4-bit storage latch and an 8421 BCD-to-7-seg-ment decoder and driver.

Key Features

  • Wide supply voltage:3.0V to 18V.
  • range High noise immunity:0.45 VDD (typ. ).
  • Low power TTL Compatibility:Fan out of 2 driving 74L or 1 driving 74LS.
  • Low power dissipation:50 nA/package (typ. ) at VDD =5.0V.
  • Latch storage.
  • Blanking input.
  • Blank for all illegal inputs.
  • Direct-drive LCD, LED and VF displays.
  • Pin-for-pin replacement for CD4056B (with pin 7 tied to Vss).
  • Pin-for-pin replacement for Motorola MC14543B DIP-16 SOP-16 TSSOP-16 Ordering I.
