Texas Instruments TLV7011DCKR

Overview

TLV7011DCKR from Texas Instruments is a single-channel, micropower voltage comparator with push-pull output, rail-to-rail input capability, 5 µA quiescent current, 260 ns propagation delay (high-to-low), and operation from 1.6 V to 6.5 V supply. It is used in battery-powered threshold detection circuits where low power and fast response are critical, such as in portable IR receivers or precision level translators.

For engineers reviewing the TLV7011DCKR datasheet, TLV7011DCKR pinout, TLV7011DCKR application, or TLV7011DCKR equivalent, key selection considerations include its SC70-5 package footprint, internal hysteresis for noise immunity, no phase reversal under overdriven inputs, and compatibility with 1.8 V/3.3 V/5 V systems across –40°C to +125°C ambient.

Technical Context

The TLV7011DCKR implements a CMOS input stage with rail-to-rail common-mode range extending 100 mV beyond VCC and down to VEE, enabling direct interfacing with sensors or logic outputs outside the supply rails. Its push-pull output drives capacitive loads up to 15 pF with 5 ns rise/fall times and sources/sinks ≥3 mA at 5 V.

It integrates a Power-on-Reset (POR) circuit that holds the output low during supply ramp-up until VCC ≥1.6 V, ensuring deterministic startup. Internal hysteresis (1.2–14 mV) eliminates oscillation near switching thresholds without external components.

FAQ

What is the maximum input voltage the TLV7011DCKR can tolerate when VCC is unpowered?

The TLV7011DCKR inputs are fault-tolerant up to 5.5 V regardless of VCC state. This allows safe connection to powered sensors or buses while the comparator's supply is off or ramping, eliminating risk of latch-up or damage during hot-swap scenarios. The 5.5 V limit is specified independently of VCC and applies to both IN+ and IN– pins.

Does the TLV7011DCKR require external hysteresis resistors for stable operation?

No, the TLV7011DCKR includes internal hysteresis (1.2–14 mV) as a fixed feature. This eliminates the need for external positive feedback components, reduces PCB area, and ensures consistent noise immunity across temperature and supply voltage. External hysteresis is unnecessary unless a specific, non-standard hysteresis value is required.

What is the output behavior of the TLV7011DCKR during power-up?

During power-up, the TLV7011DCKR's integrated Power-on-Reset (POR) circuit holds the OUT pin low (at VEE) until VCC reaches and stabilizes at ≥1.6 V. This prevents undefined or glitchy output states at startup, ensuring deterministic behavior in systems where comparator output directly controls enable lines or interrupt inputs.

Can the TLV7011DCKR operate from a 1.6 V supply while maintaining full specification performance?

Yes-the TLV7011DCKR is fully characterized from 1.6 V to 6.5 V. At 1.6 V, it maintains 5 µA quiescent current, 260 ns propagation delay (tPHL), and rail-to-rail input operation down to VEE. All electrical characteristics-including input offset, hysteresis, and output drive-are guaranteed across this full range per the datasheet's Recommended Operating Conditions table.

Is the TLV7011DCKR pin-compatible with other comparators in the TLV70xx family?

The TLV7011DCKR shares identical SC70-5 pinout with TLV7021DCKR (open-drain variant), enabling direct substitution where output topology permits. However, it is not pin-compatible with dual-channel variants (e.g., TLV7012) or different packages (X2SON, SOT-23). Always verify output configuration and load requirements before replacement.
