An 804 KB full datasheet for the tiny15, consistent with the Atmel AVR ATtiny15 8-bit microcontroller. No revision appears in the name.

Datasheet for the LM50, a single-supply analog temperature sensor whose output includes a fixed DC offset so it can report temperatures below zero without a negative…

Update package for the A8700 receiver carrying version V8.29 from 26 October 2021, about 11.3 MB in zip form.

BIOS dump named 0883A, a 16.0 MB .bin that carries only what appears to be a hexadecimal identifier with no brand or model.

Document for the BA7075, a ROHM integrated circuit, provided as a 158 KB PDF and filed as a schematic.

A 43.8 KB PDF for the 2SD2565 transistor, its name ending in _E. Although classified as a schematic, the file is most likely a datasheet, as the JIS prefix 2SD…

Short 44 KB PDF covering the 4N32 and 4N33 optocouplers, two closely related members of the 4N family that use a Darlington phototransistor output for high current…

Revision 5 of a datasheet for the 4N25 optocoupler, a 281 KB PDF. The 4N25 is one of the oldest and most common phototransistor-output isolators, often found in power…

One of the larger sheets in the set at 271 KB, this PDF is named after the 2SD2498 and serves as a transistor datasheet.

This 145 KB PDF carries the 2SD1722 part number and nothing more, so it is best treated as that transistor's datasheet.

Very small 32.3 KB PDF titled 2SK2383, listed in the schematic category but most probably a short datasheet or summary sheet for an N-channel field-effect transistor, as…

Here the 2SK1730 is documented in a 97.1 KB PDF. The 2SK prefix belongs to the Japanese JIS/JEITA register and indicates an N-channel field-effect transistor, so the…

Reference PDF of 114 KB for the 2SK1691 N-channel field-effect transistor, the 2SK code being part of the Japanese semiconductor registry.

The 2SK1434 N-channel field-effect transistor, named according to the Japanese JIS scheme where 2SK signals that device class, is documented in this 104 KB PDF.

Part reference for the 2SK242, saved as a 170 KB PDF in the schematic section. Japanese JIS designations beginning with 2SK belong to N-channel FETs, so the file is most…

PDF reference of 42.4 KB for the 2SJ578 part, listed in the schematic section. Japanese JIS coding gives the 2SJ prefix to P-channel field-effect transistors, so the…

A 164 KB PDF dedicated to the 2SD1221, recorded as a schematic in the catalogue. Japanese JIS numbering uses the 2SD prefix for NPN bipolar transistors in low-frequency…

A 144 KB PDF whose name is just the part number 2SD1190, filed as a schematic but in practice a transistor datasheet.

The 2SD1061 is the subject of this 102 KB PDF, placed in the schematic section though it reads as a part datasheet.

The 2SC4632LS gets a brief 26.9 KB PDF here, indexed as a schematic but named after a discrete semiconductor.

Indexed under schematics, the 116 KB PDF named 2SC5155 refers to a discrete semiconductor rather than a whole board.

Labelled 2SC4578, the 104 KB PDF is indexed as a schematic, though its name matches a single semiconductor part, so it is probably a datasheet.

A 128 KB PDF for the 2SC4564, filed among schematics but almost certainly a datasheet, since the name is just a JIS transistor number.

Short 88.9 KB PDF carrying the transistor number 2SC4217, filed among schematics. JEITA assigns the 2SC prefix to NPN bipolar transistors, so this should be a datasheet…

Short 30.6 KB PDF covering the 2SC5763, filed under schematics. No laptop, board or revision appears in the name, only the part designation, which in the Japanese system…

The 2SC5810 NPN transistor is covered by this 177 KB PDF, indexed as a schematic though its content is most likely the datasheet.

Covering the 2SC5320, this 124 KB PDF is indexed as a schematic but is almost certainly a datasheet for a single transistor.

Part 2SC3070 is the subject of this 91.1 KB PDF, listed among schematics. No manufacturer, package or gain grade appears in the name.
