XINLUDA · LED Display Drivers · DIP-16

XD74LS48 from XINLUDA, in a DIP-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 B input BCD input B; input high-level max/low-level thresholds are VIH 2 V min and VIL 0.8 V max.
2 C input BCD input C; TTL-compatible input with VIH 2 V min and VIL 0.8 V max.
3 LT input Active-low lamp test input that turns on all segments when low and BI/RBO is high.
4 BI/RBO bidirectional Blanking input/ripple-blanking output; forcing it low blanks all outputs, and as an output it sources up to -500 µA high and sinks 3.2 mA low on the LS48.
5 RBI input Active-low ripple-blanking input for leading/trailing zero suppression, which blanks outputs when low with BCD 0 input.
6 D input BCD input D (most significant bit); TTL-compatible input with VIH 2 V min and VIL 0.8 V max.
7 A input BCD input A (least significant bit); TTL-compatible input with VIH 2 V min and VIL 0.8 V max.
8 GND power_in Ground reference for the supply and all voltage values.
9 e output Segment e output, active-high with internal pull-up on the LS48, sinking 6 mA low-level and sourcing -100 µA high-level.
10 d output Segment d output, active-high with internal pull-up on the LS48, sinking 6 mA low-level and sourcing -100 µA high-level.
11 c output Segment c output, active-high with internal pull-up on the LS48, sinking 6 mA low-level and sourcing -100 µA high-level.
12 b output Segment b output, active-high with internal pull-up on the LS48, sinking 6 mA low-level and sourcing -100 µA high-level.
13 a output Segment a output, active-high with internal pull-up on the LS48, sinking 6 mA low-level and sourcing -100 µA high-level.
14 g output Segment g output, active-high with internal pull-up on the LS48, sinking 6 mA low-level and sourcing -100 µA high-level.
15 f output Segment f output, active-high with internal pull-up on the LS48, sinking 6 mA low-level and sourcing -100 µA high-level.
16 VCC power_in Supply voltage, 4.75 V min, 5 V nominal, 5.25 V max, with 7 V absolute maximum.
