I saw this part on a local market categorized as "unknown parts".
out of curiosity I searched
HCT38540A with no results. the marking in the first line beside TI logo reads
244 so I searched
74HCT244 which is a well known line driver with 20 pins. but this one has 38 pins.
there are 2 little metal edges around pin 11. so I thought this must be two 74HCT244 ICs connected together and the metal markings indicate pin 1 of the second IC, with common supply pins (pin 10 being GND). any Ideas about this? and if it's two 74HC244 in one case (like NE556?), why with no datasheet and an obstructed marking ?
