Texas Instruments TLV3704CPW

Overview

TLV3704CPW from Texas Instruments is a quad nanopower comparator with push-pull CMOS output, designed for ultra-low-power sensing and threshold detection in battery-powered systems. It draws only 560 nA per channel, operates from 2.5 V to 16 V, supports input common-mode voltage up to VCC + 5 V, and is rated for 0°C to 70°C commercial operation. It is used in portable battery monitoring and handheld instrumentation where quiescent current and rail-overlapping input range are critical.

For engineers reviewing the TLV3704CPW datasheet, TLV3704CPW pinout, TLV3704CPW application, or TLV3704CPW equivalent, key selection criteria include its 560 nA/channel supply current, 14-pin TSSOP package, push-pull output stage eliminating external pull-up resistors, reverse-battery protection up to 20 V, and guaranteed operation down to 2.5 V supply - all validated across the commercial temperature range.

Technical Context

The TLV3704CPW implements a precision comparator core with fail-safe inputs capable of operating 5 V above VCC without damage, enabled by internal ESD clamps and power-rail-independent biasing. Its input stage delivers sub-1 pA bias current in low common-mode regions and remains functional even when unpowered - critical for hot-swap or power-sequencing-sensitive applications.

It integrates an internal Power-On Reset (POR) circuit that holds outputs low for up to 3 ms during supply ramp-up, ensuring deterministic startup behavior. The push-pull CMOS output drives high or low actively, supporting direct interface with digital logic without external components, and exhibits typical propagation delays of 16 µs (high-to-low) and 16 µs (low-to-high) at 50 mV overdrive.

FAQ

What is the maximum input voltage allowed on TLV3704CPW pins?

The TLV3704CPW supports an input common-mode voltage range from –0.1 V to VCC + 5 V, with absolute maximum rating of ±20 V differential and 0 V to VCC + 5 V (whichever is smaller) on any input pin. This allows safe operation when sensing voltages exceeding the supply rail - for example, monitoring a 9 V battery on a 3.3 V system. The device includes internal clamps to protect against overvoltage transients.

Does TLV3704CPW require external pull-up resistors on its outputs?

No, TLV3704CPW does not require external pull-up resistors because it features a push-pull CMOS output stage. Each of its four outputs can actively drive high (to within 80 mV of VCC) or low (to within 8 mV of GND) under load, enabling direct interfacing with standard CMOS or TTL logic without additional components - reducing board area, cost, and potential leakage paths.

What is the guaranteed operating temperature range for TLV3704CPW?

The TLV3704CPW is specified for commercial-grade operation from 0°C to 70°C. This range is confirmed in the device's ordering information (C-suffix) and supported across all electrical characteristics in the datasheet, including supply current, propagation delay, and input offset voltage. For extended temperature use, TLV3704IPW (–40°C to 125°C) is the direct TSSOP-14 alternative.

How does the Power-On Reset (POR) function in TLV3704CPW?

The TLV3704CPW incorporates an internal POR circuit that activates when VCC crosses 1.5 V during power-up or power-down. It holds all four outputs low for up to 3 ms after crossing this threshold, ensuring predictable startup behavior and preventing spurious logic transitions. This feature is active regardless of input states and is intrinsic to the TLV3704CPW silicon design - no external components are needed.

Can TLV3704CPW be used with a single 2.5 V supply?

Yes, TLV3704CPW is fully specified to operate from a minimum single supply of 2.5 V across the commercial temperature range. At 2.5 V, it maintains 560 nA typical supply current per channel, functional input common-mode range (–0.1 V to 7.5 V), and valid push-pull output swing. This makes TLV3704CPW suitable for ultra-low-voltage applications such as energy-harvesting sensors and coin-cell–powered IoT endpoints.
