TSSOP-20

The TSSOP-20 is a 20-pin thin shrink small outline package with 0.65mm pitch and a 4.4 x 6.5mm body. It is the natural step up from TSSOP-14 for ICs needing more I/O. Commonly houses shift registers (74HC595), I/O expanders (PCF8574), LED drivers (TLC5940), USB interfaces, and small microcontroller variants. The thin 1.1mm profile and narrow body make it suitable for dense layouts while remaining hand-solderable with drag soldering technique.
