With regard to compaq tft450 mainboard,
P/N 00.54001.001. Rev:D
I am trying to locate the following components...9839w act14 14pin dil
designated U8 on board,and, ??77hh ??m75 cim5 8pin dil designated U47 on
board.
(I`m guessing this may be a LM75
As I am unable to locate a schematic for this
model I am not entirely sure of the function of these chips.
Can anyone help? either with a schematic or components.
Thank you.

- 74ACT14 (Hex Inverting Schmitt Trigger)
- LM75CIM-5 (Temp. Sensor with I2C-interface, 9-bit Delta-Sigma ADC and
digital over-temperature detector) The number 5 at the end means 5V.
(because there's also a 3V-version: LM75CIM-3)
