TLC27L4ACDR

TLC27L4ACDR is a Texas Instruments quad analog switch/multiplexer from the TLC27L family. It provides four independent 2:1 analog switches (four channels) whose inputs can be routed to a common output under a common two-bit select control. It’s designed for low-voltage, low-power signal routing in portable and instrumentation apps.
Key points:
- Configuration: four 2:1 analog switches (four data paths), controlled by select lines (typical S1/S0).
- Supply range: operates on a low-voltage single supply (roughly 2.7 V to 5.5 V).
- CMOS, low power with reasonable on-resistance and fast switching suitable for signal routing.
- Applications: signal routing and selection in data acquisition, audio paths, instrumentation front-ends, and other CT/analog multiplexing tasks.
- Packaging: TLC27L4ACDR indicates a specific TI package/lotting option (D-prefixed package, A/C/R variant for packaging/lead-free/reel); refer to the datasheet for exact pinout and package details.
For exact electrical specs, pinout, and recommended operating conditions, consult the TI TLC27L4ACDR datasheet.

TLC27L4ACDR is a Texas Instruments quad low-power operational amplifier. Key features:
- Four independent op-amps in one 14-pin package.
- Very low quiescent current per amplifier (low-power operation).
- Wide supply voltage range (suitable for single- or dual-supply systems).
- Input common-mode range extends to the negative rail.
- Unity-gain stable (usable as voltage followers and various amplifier configurations).
- Internally frequency-compensated for stable closed-loop performance.
- RoHS-compliant, with packaging variant indicated by DR (tape/reel) in the suffix.

14-pin SOIC package (D‑lead), RoHS/lead-free.

Pin count: 14 pins.
Function: Texas Instruments TLC27L4ACDR is a quad buffer/driver with four buffered outputs (tri-state). It provides four CMOS/TTL-compatible buffers suitable for bus buffering and isolation.

- Manufacturer: Texas Instruments (TI)
- What kind of company: An American multinational semiconductor company that designs and manufactures integrated circuits (ICs) and related components, with a focus on analog, mixed-signal, and embedded processing technologies.

Application areas: low‑power digital buffering and level shifting for microcontroller interfaces, address/data bus buffering, gating and fan‑out expansion, clock distribution, and general‑purpose digital logic in portable, consumer, and industrial electronics. Suitable for 3.3V–5V CMOS logic with low static current.
