Texas Instruments TL3016CDR

Overview

TL3016CDR from Texas Instruments is an ultrafast precision comparator IC designed for high-speed analog-to-digital interface and TTL-level signal conditioning. It delivers 7.6 ns typical propagation delay, 3 mV max input offset voltage at 25°C, and operates from single 5-V or dual ±5-V supplies with complementary latched outputs. It is used in high-resolution data acquisition systems requiring fast, low-power threshold detection.

For engineers reviewing the TL3016CDR datasheet, TL3016CDR pinout, TL3016CDR application, or TL3016CDR equivalent, key selection factors include propagation delay vs. supply current trade-off, latch-enable timing integrity, common-mode input range under single-supply operation, and compatibility with TTL logic families without level-shifting.

Technical Context

The TL3016CDR implements a bipolar differential input stage with high-gain open-loop architecture optimized for sub-10 ns switching. Its complementary outputs (Q and Q̅) are internally latched via a dedicated LATCH ENABLE terminal, enabling synchronous sampling in pipeline ADC front-ends and digital oscilloscope trigger circuits.

It supports dual ±5-V operation with ±3.75 V common-mode input range or single 5-V supply with 1.25–3.5 V common-mode range. Input bias current remains below 10 µA across temperature, and output drive capability sustains 4 mA sink at ≤600 mV low-level voltage - sufficient for direct TTL fan-out.

Key Specifications

FAQ

What is the maximum operating temperature range for the TL3016CDR?

The TL3016CDR is rated for operation from 0°C to 70°C ambient temperature. This commercial-grade specification aligns with its intended use in benchtop test equipment and non-automotive industrial instruments. The absolute maximum junction temperature is 150°C, and thermal derating begins above 25°C at 5.8 mW/°C for the SOIC package. Always verify board-level thermal design using the 725 mW power rating at TA ≤ 25°C.

Does the TL3016CDR support single-supply operation, and what is its valid input common-mode range in that configuration?

Yes, the TL3016CDR supports true single-supply operation from a 5-V rail. In this mode, its specified common-mode input voltage range is 1.25 V to 3.5 V - enabling direct interfacing with mid-rail analog signals without external biasing networks. This range is explicitly validated in the electrical characteristics table under "VICR" with VDD = 5 V, and applies across the full 0°C to 70°C operating temperature range.

How does the LATCH ENABLE function work on the TL3016CDR, and what timing constraints apply?

The LATCH ENABLE pin on the TL3016CDR is an asynchronous active-high TTL input that freezes the comparator's output state when asserted. Its 2.5 ns setup time (tsu) must be met relative to the input transition initiating propagation delay. Once latched, outputs remain stable until LATCH ENABLE is deasserted. This feature eliminates metastability in sampled-data systems and replaces external SR latches - a capability not found in pin-compatible alternatives like the LT1016.

Is the TL3016CDR pin-compatible with the LT1016, and can it be used as a drop-in replacement?

The TL3016CDR is a functional replacement for the LT1016 with identical 8-pin SOIC (D) footprint and pinout - confirmed by TI's datasheet stating "pin-for-pin functional replacement". However, it is not a drop-in replacement in all designs: the TL3016CDR draws half the supply current and adds a LATCH ENABLE pin that must be tied high or controlled, whereas the LT1016 has no such terminal. Unused LATCH ENABLE should be pulled to VCC+ via ≤1 kΩ to maintain default operation.

What are the output drive capabilities of the TL3016CDR, and how do they interface with standard TTL logic?

The TL3016CDR provides complementary TTL-compatible outputs: VOH ≥ 3.6 V at 1 mA source current and VOL ≤ 600 mV at 4 mA sink current - meeting standard TTL VIH ≥ 2.0 V and VIL ≤ 0.8 V thresholds with margin. Its outputs drive up to 10 standard TTL loads directly, eliminating buffer stages in digital test fixtures. Output current limits are ±20 mA absolute maximum, and load capacitance should remain ≤50 pF to preserve 7.6 ns propagation performance.
