Nexperia · Latches · TSSOP-16

74HC259PW-Q100 from Nexperia, in a TSSOP-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 A0 input Address input A0; selects addressed latch in addressable latch mode.
2 A1 input Address input A1; selects addressed latch in addressable latch mode.
3 A2 input Address input A2; selects addressed latch in addressable latch mode.
4 Q0 output Latch output Q0; follows data input D when latch is addressed and LE is active LOW.
5 Q1 output Latch output Q1; follows data input D when latch is addressed and LE is active LOW.
6 Q2 output Latch output Q2; follows data input D when latch is addressed and LE is active LOW.
7 Q3 output Latch output Q3; follows data input D when latch is addressed and LE is active LOW.
8 GND power_in Ground reference voltage (0 V).
9 Q4 output Latch output Q4; follows data input D when latch is addressed and LE is active LOW.
10 Q5 output Latch output Q5; follows data input D when latch is addressed and LE is active LOW.
11 Q6 output Latch output Q6; follows data input D when latch is addressed and LE is active LOW.
12 Q7 output Latch output Q7; follows data input D when latch is addressed and LE is active LOW.
13 D input Data input; written to addressed latch when LE is active LOW.
14 LE input Latch enable input (active LOW); enables data latching when LOW.
15 MR input Conditional reset input (active LOW); forces all outputs LOW when active.
16 VCC power_in Supply voltage; 2.0 V to 6.0 V specified range.
