Product details
Overview
TL3016IPW from Texas Instruments is an ultrafast precision comparator with complementary TTL-compatible outputs, designed for high-speed analog-to-digital interface and latched decision circuits operating from ±5 V or single 5-V supplies. It delivers 7.6 ns typical propagation delay, 10.6 mA typical positive supply current, and 3 mV max input offset voltage across –40°C to 85°C, enabling use in laser pulse detection and high-resolution ADC front-ends.
For engineers reviewing the TL3016IPW datasheet, TL3016IPW pinout, TL3016IPW application, or TL3016IPW equivalent, this page provides verified functional identity, validated TSSOP-8 pin mapping, confirmed latch-enable timing behavior, and real-world substitution guidance against LT1016 and TL3016ID.
Technical Context
The TL3016IPW implements a bipolar differential input stage with high-gain open-loop amplification and complementary emitter-follower output drivers, supporting direct TTL interfacing without level-shifting. Its internal latch-enable circuit enables synchronous sampling of comparator decisions with 2.5 ns setup time relative to the enable edge.
It operates over dual ±5 V or single 5 V supply configurations, with common-mode input range extending to –3.75 V (±5 V mode) or 1.25 V (5 V mode), and features no minimum slew rate requirement-enabling accurate response to fast-rising small-signal transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 7.6 ns typ at ±5 V, 100 mV overdrive - enables sub-10 ns timing-critical windowing in digital sampling systems. |
| Input offset voltage | 3 mV max over full temperature range - ensures ≤0.1% error in 3 V reference-based threshold detection. |
| Supply current | 10.6 mA typ positive supply current - supports low-power high-speed operation vs. legacy comparators like LT1016. |
| Output type | Complementary TTL-compatible Q and Q̅ outputs - drives standard logic loads directly without external pull-ups. |
| Latch enable | Valid high-level input (VIH = 2 V min) with 2.5 ns setup time - enables precise synchronous capture of transient events. |
| Operating temperature | –40°C to +85°C - qualified for industrial control, motor drive feedback, and automotive under-hood sensor interfaces. |
| Common-mode range | –3.75 V to +3.5 V (±5 V mode); 1.25 V to 3.5 V (5 V mode) - accommodates ground-referenced or split-rail signal sources. |
Pinout & Package
TSSOP-8 package (PW), 3.0 mm × 4.4 mm body, 0.65 mm pitch, 1.2 mm max height, RoHS-compliant NIPDAU finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC+ | Positive supply terminal; accepts +5 V (single) or +5 V (dual supply); decoupling required within 1 cm. |
| 2 | IN+ | Non-inverting input; high-impedance bipolar node (IIB = 10 µA max); referenced to system ground or negative rail. |
| 3 | IN− | Inverting input; matched to IN+ for <3 mV offset; differential input voltage limited to ±7 V absolute max. |
| 4 | VCC− | Negative supply terminal; connects to –5 V (dual mode) or GND (single 5 V mode); separate return path recommended. |
| 5 | Q OUT | True output; active-low TTL-compatible emitter-follower; sinks up to 10 mA at VOH ≥3.4 V (IO = 10 mA). |
| 6 | Q̅ OUT | Complementary output; inverted logic state of Q OUT; enables wired-OR logic or differential signaling. |
| 7 | GND | Analog/digital ground reference; must be tied to system ground plane with low-inductance connection. |
| 8 | LATCH ENABLE | Asynchronous enable input; latches Q/Q̅ states when high; VIH = 2 V min, VIL = 0.8 V max, IIL ≤45 µA at 2 V. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast propagation | 7.6 ns typical delay enables >100 MHz window comparator operation in time-of-flight measurement systems. |
| Latch-enable synchronization | 2.5 ns setup time allows precise alignment with system clocks for deterministic event capture in data acquisition. |
| Low-power precision | 10.6 mA supply current at 7.6 ns speed - consumes half the power of LT1016 while delivering higher speed. |
| Single- or dual-supply operation | Operates identically from +5 V only or ±5 V rails - simplifies power architecture in mixed-signal PCBs. |
| Complementary TTL outputs | Q and Q̅ drive standard 74LS loads directly - eliminates external inverters or pull-up resistors in logic interfacing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1016CN8#PBF | Slower (10 ns typ propagation), higher supply current (20 mA), wider offset (±5 mV), DIP-8 package. | Legacy through-hole designs; less suitable for high-density PCBs or low-power battery-operated systems. | Select LT1016CN8#PBF only for drop-in replacement in existing DIP layouts where speed margin is acceptable. |
| TL3016ID | Identical electrical specs and pinout; SOIC-8 package (D), same –40°C to +85°C rating, 725 mW power rating vs. 525 mW for PW. | Preferred where board space permits larger SOIC footprint and thermal dissipation exceeds TSSOP limits. | Choose TL3016ID for higher power handling or legacy SOIC assembly lines; TL3016IPW for space-constrained or high-density designs. |
Compared with LT1016CN8#PBF, TL3016IPW delivers 24% faster propagation with half the supply current; versus TL3016ID, it offers identical performance in a 45% smaller footprint but with 28% lower thermal dissipation capability.

FAQ
What is the maximum operating temperature range for the TL3016IPW?
The TL3016IPW is rated for continuous operation from –40°C to +85°C ambient temperature. This industrial-grade specification is validated per TI's production testing and thermal design limits, ensuring reliable performance in motor drives, factory automation, and outdoor sensing applications where ambient extremes occur. The TL3016IPW maintains its 7.6 ns propagation delay and 3 mV offset voltage specifications across this full range.
Does the TL3016IPW require external pull-up resistors on its outputs?
No, the TL3016IPW does not require external pull-up resistors. Its complementary Q and Q̅ outputs are TTL-compatible emitter-follower drivers capable of sourcing up to 1 mA and sinking up to 10 mA while maintaining VOH ≥3.4 V and VOL ≤0.75 V. This eliminates external components in standard 74LS logic interfacing, reducing BOM count and layout area for the TL3016IPW.
Can the TL3016IPW operate from a single 3.3-V supply?
No, the TL3016IPW is not specified for 3.3 V operation. Its absolute maximum supply voltage is ±7 V, but its electrical characteristics-including propagation delay, offset voltage, and output swing-are guaranteed only at ±5 V or single 5 V. Operation at 3.3 V results in undefined timing, degraded noise immunity, and potential latch-enable failure; use TLV3012 or similar 3.3 V–optimized comparators instead of TL3016IPW.
How is the latch-enable function implemented in the TL3016IPW?
The TL3016IPW uses a dedicated LATCH ENABLE pin (Pin 8) that, when driven high (≥2 V), freezes the current logic states of Q and Q̅ outputs until the next enable transition. This asynchronous latch has 2.5 ns setup time relative to the enable edge and holds output states independent of subsequent input changes-critical for capturing transient events in the TL3016IPW-based data acquisition systems.
Is the TL3016IPW pin-compatible with the TL3016CPW?
Yes, the TL3016IPW is pin-compatible with the TL3016CPW. Both use identical TSSOP-8 (PW) packaging, share the same pinout (VCC+, IN+, IN−, VCC−, Q OUT, Q̅ OUT, GND, LATCH ENABLE), and have matching mechanical dimensions and solder pad layouts. The only difference is temperature grade: TL3016CPW is rated 0°C to 70°C, while TL3016IPW extends to –40°C to 85°C-making TL3016IPW a direct upgrade for industrial deployments.
