CD4028BE

Texas Instruments · Signal Switches, Multiplexers, Decoders · DIP-16

CD4028BE from Texas Instruments, 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	4	output	Buffered decoded output 4, goes high when the BCD input code equals 4.
2	2	output	Buffered decoded output 2, goes high when the BCD input code equals 2.
3	0	output	Buffered decoded output 0, goes high when the BCD input code equals 0.
4	7	output	Buffered decoded output 7, goes high when the BCD input code equals 7.
5	9	output	Buffered decoded output 9, goes high when the BCD input code equals 9 (low in octal mode).
6	5	output	Buffered decoded output 5, goes high when the BCD input code equals 5.
7	6	output	Buffered decoded output 6, goes high when the BCD input code equals 6.
8	VSS	power_in	Ground supply terminal (VSS), 0 V reference for VDD of 3 V to 18 V.
9	8	output	Buffered decoded output 8, goes high when the BCD input code equals 8 (low in octal mode).
10	A	input	BCD input A (least significant bit), CMOS-protected input limited to -0.5 V to VDD+0.5 V.
11	D	input	BCD input D (most significant bit); D = 0 selects binary-to-octal decoding on A to C.
12	C	input	BCD input C, CMOS-protected input limited to -0.5 V to VDD+0.5 V.
13	B	input	BCD input B, CMOS-protected input limited to -0.5 V to VDD+0.5 V.
14	1	output	Buffered decoded output 1, goes high when the BCD input code equals 1.
15	3	output	Buffered decoded output 3, goes high when the BCD input code equals 3.
16	VDD	power_in	Positive supply voltage, recommended 3 V to 18 V, absolute maximum -0.5 V to +20 V.
