74HC4511D

Nexperia · Signal Switches, Multiplexers, Decoders · SOIC-16

74HC4511D from Nexperia, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 B input BCD address input used to define the decimal digit display along with A, C, D inputs.
2 C input BCD address input used to define the decimal digit display along with A, B, D inputs.
3 LT input Lamp test input (active LOW); drives all segment outputs HIGH when LOW, overriding all other inputs.
4 BI input Ripple blanking input (active LOW); drives all segment outputs LOW when LOW and LT is HIGH.
5 LE input Latch enable input (active LOW); latches BCD input data when transitioning from LOW to HIGH; segment outputs remain stable when LE is HIGH.
6 D input BCD address input used to define the decimal digit display along with A, B, C inputs.
7 A input BCD address input used to define the decimal digit display along with B, C, D inputs.
8 GND power_in Ground (0 V) reference for all signal levels.
9 e output 7-segment output capable of 10 mA drive for common cathode LED display segments.
10 d output 7-segment output capable of 10 mA drive for common cathode LED display segments.
11 c output 7-segment output capable of 10 mA drive for common cathode LED display segments.
12 b output 7-segment output capable of 10 mA drive for common cathode LED display segments.
13 a output 7-segment output capable of 10 mA drive for common cathode LED display segments.
14 g output 7-segment output capable of 10 mA drive for common cathode LED display segments.
15 f output 7-segment output capable of 10 mA drive for common cathode LED display segments.
16 VCC power_out Supply voltage; 2.0 V to 6.0 V for 74HC4511 or 4.5 V to 5.5 V for 74HCT4511.
