今日分享：TI 产品SN74AHC1G00 ，单通道双输入正与非门，实现 功能： Y = A• B 或 Y = A + B。该产品最早的数据手册可追溯到1996年，且至今仍在售。


The simplest possible microchip, SN74AHC1G00,  made by Texas Instruments. Die size 520x420 µm.



After etching 2(!) metal layers, we can see that chip area occupied mostly by pads, input protection, and output transistors. Funny rainbow things below pads - partially etched insulating dielectric masked by what's left from gold bond wires.

三款经典的logic shift register, 分别来自NXP, fairchild, OnSemic.

NXP 74HC595 - yet another standard logic shift register.
Die size 953x866 µm, 2µm manufacturing technology.


Fairchild 74VHC595 - standard logic chip, 8-bit shift register.
Die size 800x690 µm. 800nm manufacturing technology.


ON Semiconductor 74HC595 is a 8-bit shift register (serial-in parallel-out).
That's incredible: 47 years passed since 7400 TTL logic introduction - it is still manufactured and used in new products.

今日分享：
UTC LM2940L-5.0 - 1A low-dropout linear regulator.
Apparently 5 contacts at the bottom-right were used to fine-tune output voltage by burning fuses between them.
