Product specification
Quad 2-input multiplexer; 3-state
74HC/HCT257
R
EPAIRING SOLDERED JOINTS
Fix the component by first soldering two diagonally- opposite end leads. Use only a low voltage soldering iron (less
than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300
°
C. When using a
dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320
°
C.
