Nexperia · Signal Switches, Multiplexers, Decoders · TSSOP-24

74HCT4514PW from Nexperia, in a TSSOP-24. 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 LE input Latch enable input (active HIGH): when LOW, the last data on A0 to A3 is stored in the latches and the outputs remain stable.
2 A0 input Binary-weighted address input A0 for selecting one of the 16 outputs; it is latched when LE goes LOW.
3 A1 input Binary-weighted address input A1 for selecting one of the 16 outputs; it is latched when LE goes LOW.
4 Q7 output Multiplexer output Q7 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
5 Q6 output Multiplexer output Q6 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
6 Q5 output Multiplexer output Q5 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
7 Q4 output Multiplexer output Q4 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
8 Q3 output Multiplexer output Q3 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
9 Q1 output Multiplexer output Q1 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
10 Q2 output Multiplexer output Q2 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
11 Q0 output Multiplexer output Q0 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
12 GND power_in Ground (0 V) reference for all voltages.
13 Q13 output Multiplexer output Q13 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
14 Q12 output Multiplexer output Q12 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
15 Q15 output Multiplexer output Q15 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
16 Q14 output Multiplexer output Q14 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
17 Q9 output Multiplexer output Q9 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
18 Q8 output Multiplexer output Q8 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
19 Q11 output Multiplexer output Q11 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
20 Q10 output Multiplexer output Q10 (active HIGH); it is HIGH only when E is LOW and the latched address selects it.
21 A2 input Binary-weighted address input A2 for selecting one of the 16 outputs; it is latched when LE goes LOW.
22 A3 input Binary-weighted address input A3 for selecting one of the 16 outputs; it is latched when LE goes LOW.
23 E input Enable input (active LOW): when LOW the latched output selected by the address is HIGH, and when HIGH all outputs are LOW without affecting the latch.
24 VCC power_in Supply voltage: recommended 2.0 V to 6.0 V for 74HC4514 and 4.5 V to 5.5 V for 74HCT4514, with an absolute maximum of 7 V.
