XD74LS248

XINLUDA · LED Display Drivers · DIP-16

XD74LS248 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; TTL-compatible, high-level input at least 2 V and low-level at most 0.8 V.
2 C input BCD input C; TTL-compatible, high-level input at least 2 V and low-level at most 0.8 V.
3 LT input Active-low lamp test input; with BI/RBO high, a low level turns on all segment outputs.
4 BI/RBO bidirectional Blanking input (active low) that forces all segment outputs off, or ripple-blanking output, with IOL 3.2 mA max and IOH -50 µA max on the 247 spec.
5 RBI input Active-low ripple-blanking input for leading/trailing-edge zero suppression; blanks outputs when low with BCD inputs at zero.
6 D input BCD input D (most significant bit); TTL-compatible, high-level input at least 2 V and low-level at most 0.8 V.
7 A input BCD input A (least significant bit); TTL-compatible, high-level input at least 2 V and low-level at most 0.8 V.
8 GND power_in Ground, the network ground terminal for all voltage values.
9 e output Segment e output, active-high with internal pull-up on the 'LS248.
10 d output Segment d output, active-high with internal pull-up on the 'LS248.
11 c output Segment c output, active-high with internal pull-up on the 'LS248.
12 b output Segment b output, active-high with internal pull-up on the 'LS248.
13 a output Segment a output, active-high with internal pull-up on the 'LS248.
14 g output Segment g output, active-high with internal pull-up on the 'LS248.
15 f output Segment f output, active-high with internal pull-up on the 'LS248.
16 VCC power_in Supply voltage, 4.75 V to 5.25 V recommended (5 V nominal), 7 V absolute maximum.
