TLC339CPW

TLC339CPW Description

The TLC339CPW from Texas Instruments is a quad general-purpose comparator from the LinCMOS™ series, designed for precision analog signal processing. Packaged in a 14-pin TSSOP (Tube), this surface-mount IC operates over a 3V to 16V supply range, making it versatile for both single and dual-voltage applications. With a low quiescent current of 100µA (max) and ultra-low input bias current (5pA @ 5V), it excels in power-sensitive designs. The device features a fast propagation delay of 4.5µs (max) and high CMRR (84dB), ensuring reliable performance in noisy environments. Though marked Obsolete, it remains ROHS3 Compliant and REACH Unaffected, suitable for legacy or low-power systems.

TLC339CPW Features

• Low Power Consumption: 100µA max quiescent current ideal for battery-operated devices.
• High Precision: 5mV max input offset voltage at 10V for accurate comparisons.
• Robust Noise Immunity: 84dB CMRR minimizes common-mode interference.
• Wide Voltage Range: 3V–16V operation supports diverse power configurations.
• Fast Response: 4.5µs propagation delay balances speed and efficiency.
• Compact & Reliable: 14-TSSOP package with MSL1 (Unlimited) moisture sensitivity.

TLC339CPW Applications

• Battery-Powered Systems: Portable electronics, sensors, and IoT devices benefit from its low current draw.
• Signal Conditioning: Precision window comparators, zero-crossing detectors.
• Industrial Control: Overvoltage/undervoltage monitoring due to high CMRR.
• Automotive Electronics: Stable performance in 12V systems (e.g., threshold detection).
• Legacy Upgrades: Replacement for older comparators in maintenance projects.

Conclusion of TLC339CPW

The TLC339CPW combines low power, precision, and noise resilience, making it a strong choice for analog comparison tasks despite its obsolete status. Its wide supply range and fast response suit both industrial and consumer applications, particularly where power efficiency is critical. Engineers seeking a cost-effective, RoHS-compliant solution for legacy designs or low-voltage systems will find this IC a reliable option.
