Product Overview

The HEF4543BT is a BCD to 7-segment Latch/Decoder/Driver for liquid crystal and LED displays. It has four address inputs (D0 to D3), an active low LE\, an active high blanking input (BL), an active high phase input (PH) and seven buffered segment outputs (Qa to Qg). The circuit provides the function of a 4-bit storage latch and an 8-4-2-1 BCD to 7-segment decoder/driver. It can invert the logic levels of the output combination. The phase (PH), blanking (BL) and LE\ inputs are used to reverse the function table phase, blank the display and store a BCD code, respectively. For liquid crystal displays, a square-wave is applied to PH and the electrical common back-plane of the display. The outputs of the device are directly connected to the segments of the liquid crystal. It operates over a recommended VDD power supply range of 3 to 15V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS or another input.
  • Fully static operation
  • Standardized symmetrical output characteristics
  • Complies with JEDEC standard JESD 13-B

Product Information

:  BCD to 7 Segment Decoder / Driver / Latch
Manufactured in the 90’s by Philips 

These came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co. They are stored with us still sealed in original packaging (unopened boxes and tubes) and are in pristine condition. However having been in storage for some years (date code 9333) we have classified them as ‘new other’.

As many of our lines come in to us as surplus – sometimes from high end ‘Milspec’ type manufacturers we try to pass on our savings to our customers – often selling industrial grade or military spec components at a fraction of their original cost.
