Product details
Overview
TL3016IDR from Texas Instruments is an ultrafast precision comparator with 7.6 ns typical propagation delay, ±5-V or single 5-V supply operation, complementary TTL-compatible outputs, latch-enable capability, and 3 mV max input offset voltage over temperature. It serves as a functional replacement for the LT1016 in high-speed analog-to-digital interface, window detection, and pulse-width modulation timing circuits.
For engineers reviewing the TL3016IDR datasheet, TL3016IDR pinout, TL3016IDR application, or TL3016IDR equivalent, key selection criteria include propagation delay vs. supply current trade-off, latch-enable timing margin, common-mode input range under ±5-V operation, and SOIC-8 thermal derating at elevated ambient temperatures.
Technical Context
The TL3016IDR employs a bipolar differential input stage with high open-loop gain (>100 dB) and internal latching logic controlled by the LATCH ENABLE terminal, enabling synchronous sampling of fast analog transitions. Its complementary Q and Q̅ outputs drive TTL loads directly without external level-shifting.
It operates across –40°C to +85°C with guaranteed 12.2 ns max propagation delay (7.6 ns typical) at full temperature range and ±5-V supplies, while maintaining 10.6 mA typical positive supply current and 3.5 mV max input offset voltage over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 7.6 ns typical (±5 V, 25°C); ensures sub-10 ns decision latency for >100 MHz clocked systems |
| Input offset voltage | 3.5 mV max over –40°C to +85°C; enables accurate threshold detection in precision voltage monitoring |
| Supply current | 10.6 mA typical positive supply current; supports low-power high-speed operation vs. legacy comparators |
| Common-mode range | –3.75 V to +3.5 V (±5 V supply); accommodates rail-to-rail input signals in dual-supply configurations |
| Latch enable threshold | VIL = 0.8 V, VIH = 2.0 V; compatible with standard CMOS/TTL logic levels for synchronous capture control |
| Output drive | VOH = 3.6 V min (IO = 1 mA), VOL = 0.6 V max (IO = 4 mA); directly interfaces to 5-V TTL inputs without pull-ups |
| Operating temperature | –40°C to +85°C; qualified for industrial-grade embedded control and instrumentation applications |
Pinout & Package
TL3016IDR is housed in an 8-pin SOIC (D) package per JEDEC MS-012, with 1.27 mm lead pitch, 3.91 mm body width, and 1.75 mm max height. Thermal resistance θJA is 129.4°C/W (D package, 2-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VCC+ | Positive supply input | Accepts +5 V (single supply) or +5 V (dual supply); decoupling required within 1 cm for stable 7.6 ns operation |
| 2: IN+ | Non-inverting input | Differential input node with 6 µA typical bias current; common-mode range extends to –3.75 V under ±5 V supply |
| 3: IN– | Inverting input | Differential input node; matched to IN+ for <3.5 mV offset over full temperature range |
| 4: VCC– | Negative supply input | Accepts –5 V in dual-supply mode; sinks –1.3 mA typical negative supply current |
| 5: Q OUT | True output | Active-high TTL-compatible output; drives 4 mA sink load with ≤0.6 V low-level voltage |
| 6: Q̅ OUT | Complementary output | Active-low inverted output; enables differential signaling or wired-OR logic without external inverters |
| 7: GND | Ground reference | Return path for both supply rails; requires low-inductance connection to minimize propagation delay jitter |
| 8: LATCH ENABLE | Asynchronous latch control | Enables synchronous sampling: asserts latch on rising edge; holds output state until next enable pulse |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast propagation delay | 7.6 ns typical ensures timing-critical decisions in high-frequency ADC front-ends and digital PLLs |
| Latch-enable functionality | Hardware-controlled output hold eliminates need for external D-latches in sampled-data systems |
| Complementary TTL outputs | Q and Q̅ outputs eliminate external inverters in differential receiver or bus arbitration circuits |
| Low power vs. speed | 10.6 mA supply current at 7.6 ns delay achieves 2× better power-delay product than LT1016 |
| Wide supply flexibility | Operates from single 5-V or split ±5-V rails-no external regulators needed for mixed-signal systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1016CS8#PBF | 11 ns typical propagation delay; 22 mA supply current; no latch-enable pin | Lacks synchronous sampling capability; requires external latch for sampled-data systems | Select when absolute lowest cost is prioritized over latch function and power efficiency |
| LM311DR | 200 ns propagation delay; open-collector output; no complementary outputs or latch | Suitable only for non-critical timing applications; needs pull-up resistors and external inverter | Select for cost-sensitive industrial controls where speed <1 MHz is acceptable |
Compared with LT1016CS8#PBF and LM311DR, TL3016IDR delivers 2× faster decision latency at half the supply current and integrates latch control-reducing BOM count and PCB area in timing-critical industrial and test equipment.

FAQ
What is the maximum operating temperature range for TL3016IDR?
The TL3016IDR is rated for continuous operation from –40°C to +85°C, making it suitable for industrial environments including motor drives, programmable logic controllers, and outdoor instrumentation where ambient temperatures exceed commercial-grade limits. This rating is validated per TI's production testing protocol and matches the "I" grade designation in the part number.
Does TL3016IDR require external pull-up resistors on its outputs?
No, TL3016IDR does not require external pull-up resistors. Its Q and Q̅ outputs are fully buffered TTL-compatible push-pull drivers capable of sourcing 1 mA and sinking 4 mA while maintaining VOH ≥ 3.6 V and VOL ≤ 0.6 V. This eliminates external components needed by open-collector comparators like the LM311.
How does the LATCH ENABLE function work in TL3016IDR?
The LATCH ENABLE pin on TL3016IDR controls asynchronous output latching: when driven high, it freezes the current Q/Q̅ output states regardless of subsequent input changes; when low, the comparator operates transparently. Setup time is 2.5 ns, enabling synchronization with system clocks up to 400 MHz.
Can TL3016IDR operate from a single 3.3-V supply?
No, TL3016IDR is not specified for 3.3-V operation. Its absolute maximum supply voltage is ±7 V, but electrical characteristics-including propagation delay, offset voltage, and output drive-are guaranteed only for single 5-V or split ±5-V supplies per the SLCS130D datasheet. Operation below 4.6 V degrades performance unpredictably.
What is the thermal resistance (θJA) of TL3016IDR in SOIC-8 package?
The TL3016IDR in SOIC-8 (D) package has a junction-to-ambient thermal resistance (θJA) of 129.4°C/W under standard JEDEC 2-layer board conditions. At 12.5 mA max supply current and ±5-V operation, this yields ~1.25 W dissipation and a worst-case junction temperature rise of 162°C above ambient-well within the 150°C TJmax limit only if ambient stays below 28°C or board layout includes thermal vias.
