Overview

Description

TLC542IDWR is a Texas Instruments device from the TLC542 family. It is a quad digital buffer/driver designed to buffer and drive signals between logic blocks, often used to increase fan-out and isolate devices on a bus. It provides tri‑state (high-impedance) outputs, making it suitable for bus sharing and interfacing different logic levels. The device is built in a surface-mount 14-pin package (IDWR indicates the reel/tape-and-reel variant of the SOIC-14 style).
Key takeaways:
- Purpose: digital buffering/drive for logic signals
- Outputs: tri-state (allows bus sharing)
- Packaging: 14-pin SOIC in reel format (IDWR)
- Applications: microcontroller I/O interfacing, level shifting, bus buffering
For exact electrical specs (supply voltage, input/output drive, propagation delay, maximum fan-out) and pinout, consult the TLC542IDWR datasheet.

Features

TLC542IDWR features (concise):
- Dual CMOS operational amplifiers
- Rail-to-rail input and output
- Single-supply operation: 2.7 V to 16 V
- Unity-gain stable
- Very low input bias current and low noise
- Low quiescent current (CMOS design)
- Wide temperature range: -40°C to +125°C
- 8-pin small-outline package (SOIC), DWR; Tape & Reel available
Typical uses: battery-powered sensors, signal conditioning, audio/low-noise applications.

Package

An 8-pin SOIC (Plastic Small-Outline) package, Tape-and-Reel.

Pinout

Pin count: 8 pins (8-pin SOIC, package suffix IDWR).
Function: Dual operational amplifier—the TLC542IDWR contains two general-purpose op-amps in one package (single-supply capable).

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI)
- What kind of company: American multinational semiconductor company that designs and manufactures analog and mixed-signal ICs, digital processing, sensors, and related semiconductor products.

Application

General-purpose dual op-amp; common applications include:
- Sensor conditioning and buffering (temperature, light, pressure, etc.)
- Gain stages and differential/summing amplifiers
- Active filters (low/high/band-pass, Sallen–Key)
- Integrators and oscillators
- DC precision front ends for portable instrumentation
- Audio preamplification and general analog signaling in consumer electronics

Equivalent

Equivalents depend on the device function (op-amp, DAC/ADC, buffer) and supply. Please confirm the exact function of TLC542IDWR and preferred vendors (TI, Analog Devices, Microchip). With that, I’ll provide direct cross‑references and package details.
