CD4543BPWR

Texas Instruments · LCD Drivers · TSSOP-16

CD4543BPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 LD input Latch Disable input; when LD=0 the four input latches are transparent and BCD data is decoded; when LD=1 the latches hold the last BCD code and inputs are ignored.
2 C input BCD data input C (bit 2); one of four BCD inputs decoded to drive the seven-segment outputs; all inputs protected by CMOS protection network.
3 B input BCD data input B (bit 1); one of four BCD inputs decoded to drive the seven-segment outputs; all inputs protected by CMOS protection network.
4 D input BCD data input D (bit 3, MSB); one of four BCD inputs decoded to drive the seven-segment outputs; all inputs protected by CMOS protection network.
5 A input BCD data input A (bit 0, LSB); one of four BCD inputs decoded to drive the seven-segment outputs; all inputs protected by CMOS protection network.
6 Ph input Phase input; apply square wave for LCD operation; connect to VSS (Ph=0) for common-cathode LED or to VDD (Ph=1) for common-anode LED; when LD=1 outputs are the inverse of normal combinations.
7 BL input Blanking input; when BL=1 and LD=0, all seven segment outputs are forced off regardless of BCD input code.
8 VSS power_in Negative supply (GND) reference, 0 V; supply voltage range VDD−VSS = 3 V min to 18 V max.
9 a output Seven-segment display driver output for segment a (top horizontal); output polarity determined by Ph input; capable of driving TTL loads or one low-power Schottky load.
10 b output Seven-segment display driver output for segment b (upper-right vertical); output polarity determined by Ph input; capable of driving TTL loads or one low-power Schottky load.
11 c output Seven-segment display driver output for segment c (lower-right vertical); output polarity determined by Ph input; capable of driving TTL loads or one low-power Schottky load.
12 d output Seven-segment display driver output for segment d (bottom horizontal); output polarity determined by Ph input; capable of driving TTL loads or one low-power Schottky load.
13 e output Seven-segment display driver output for segment e (lower-left vertical); output polarity determined by Ph input; capable of driving TTL loads or one low-power Schottky load.
14 g output Seven-segment display driver output for segment g (middle horizontal); output polarity determined by Ph input; capable of driving TTL loads or one low-power Schottky load.
15 f output Seven-segment display driver output for segment f (upper-left vertical); output polarity determined by Ph input; capable of driving TTL loads or one low-power Schottky load.
16 VDD power_in Positive supply voltage; operating range 3 V to 18 V (full package temperature range); absolute maximum −0.5 V to +20 V.

CAD (KiCad official)

  • Symbol: CD4543BPWR
  • Footprint: Package_SO:TSSOP-16_4.4x5mm_P0.65mm
  • 3D model: TSSOP-16 (KiCad packages3D, STEP)
  • 3D model files: cd4543bpwr-etched.step / cd4543bpwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cd4543bpwr.step / cd4543bpwr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
